The research also investigated the issue of moisture saturation into the rock core. Testing was completed using a suite of seven different kinds of rock that ranged from highly competent granite and dolomites to highly permeable sandstone and blast furnace slag that contained a large volume of internal pore space. The effect of adding 10% ground rubber (by weight) to fresh and aged BOF slag on the long-term swelling behavior of the mixtures was studied as well.^ The optimum moisture content and maximum dry unit weight of BOF slag were in the ranges of 4-8% and 19.5-21.8 kN/m3, respectively. These were combined with known data for thermal conductivity, bulk density and moisture content of the Sherwood Sandstone regolith. This is followed by a second part proposing the methodology of geostatistical modelling of the rock densities which is suggested as a mathematically supported approach for choosing optimal sampling grids for density samples. The grain density is the actual density of the particles, which might be a mineral. FAQ | However the determination of an accurate density for some rock materials can difficult. The maximum particle size of the soil was d = 0.5 mm. In [4] the impact adiabatic curves of four fractions of dry sand in the pressure range from 1 to 6 GPa and two fractions of watersaturated sand in the range from 2 to 12 GPa were obtained. la: a cuvette with a steel bottom 6 and organic-glass walls was filled with sandy soil i in which strips of copper foil 2 of cross section 0.i  5 ram, a flat charge of plastic explosive 3 of thickness 2m m, separated from the soil by a lavsan film 4 of thickness 0.2 man, and copper wires 5 of diameter 1 mm were placed.

Given a porosity and specific fluid, density can be easily calculated if the mineral or grain density is known. The ranges of the moisture content (4.40 – 36.25%), bulk density (1.11 – 2.08 gcm^(-3)), specific gravity (1.69 – 2.71) and free swell (0.0 – 106.3%) of the soil layers directly underlying the buildings suggest that the structural failures are most likely initiated by differential settlement caused by significant variation laterally in the compaction of the soils and clay swelling. 2017, GeoSci Developers. The effects of gradation on the engineering properties of both fresh and aged steel slag samples were assessed.^ Various mixtures of steel slag [BOF and EAF(L)] and Class-C fly ash were also investigated. bulk specific weight and density. It is defined as the mass of many particles of the material divided by the total volume they occupy. Open The width of the assemblage in the direction of the x-ray photography was 52 ran, touching every 4 mm the organic-glass side walls of the cuvette. 8 is a fundamental relation used throughout the earth sciences to calculate rock density.

The porosity, , is the fractional pore volume of a rock (for example the black zone in the cross section of a sedimentary rock to the right). The particle density of the materials used in this research were determined using an automated helium gas pycnometer, which is considered an industry standard. 1. POROSITY AND BULK DENSITY OF SEDIMENTARY ROCKS By G. EDWARD MANGER ABSTRACT More than 900 items of porosity and bulk density data for sedimentary rocks have been tabulated. Home Unconfined compression tests were performed after various curing times to evaluate the strength gain characteristics of the mixtures. Bulk density includes both the grains and the interstitial spaces. The results showed that the electrical resistivities of the subsoil at shallow depths underlying the buildings in the areas range from 2 to 1100  and this range encompass the range for Sandy Silty Clay, Coarse Sand and clay respectively. The flotation method was used to show that, for three contrasting soils, clod wet bulk density is independent of clod size. Bulk Density Chart. A diagram of the design of the experiments is given in Fig. 7 m. Analysis of the loss of elements, compared to bedrock using mass balance calculations (τ) showed that all the calcite and gypsum cement had been removed to depths of >3 m. Thus the major difference between the SR and the underlying saprolite was that the former exists as loose sand as opposed to a semi-durable rock. Accessibility Statement, Dissertations, Master's Theses and Master's Reports, Dissertations, Master's Theses and Master's Reports - Open. The results of the long-term swelling tests on steel slag and Class-C fly ash mixtures showed that the addition of 10% Class-C fly ash suppressed the swelling of both BOF and EAF(L) slag samples to negligible levels. Home | The thickness of the soil layer above the explosive charge and beneath it was -15 mm. The main problem in determining the bulk density of rock core is obtaining an accurate estimate of the rock core’s total volume. The main problem in determining the bulk density of rock core is obtaining an accurate estimate of the rock core’s total volume. adiabatic curve for dry sand with an initial density of p00 = 1.66 g/cm s in the 100 MPa-5 GPa pressure range, as well as the dependence of the mass velocity of particles in the discharge wave during the emergence of a plane impact wave (IW) onto an open surface ul on the mass velocity in an incident IW u in the 50-800 m/sec range. pozzolan for use in concrete, and reduce greenhouse gas emissions due to the reduced use of cement needed per unit concrete due to the replacement. 9 is shown in Fig. List of Bulking/Swell factors for various materials. wet bulk density with an accuracy of ± 0.05 g cm-8. (1) Main mineral component in the coral limestone is calcite, often contains dolomite or quartz. The chloride transport is described by moisture diffusivity and chloride diffusion coefficient. The investigation of the compressibility of dry, broken sandy soil with P00 = 1.68 g/cm3 under impact-wave loading in the pressure region of 0.38-7.84 GPa was carried out with aid of the x-ray diffraction method on an ERIDAN-3 apparatus. We tested this theory by developing a Monte Carlo simulation based on a simplified version of the Stefan equation. A BD of less than or equal to 1.3 g cm −3 is good, between 1.3 and 1.55 g cm −3 is fair, and greater than 1.8 g cm −3 is considered extremely bad. Bulk density, also called apparent density or volumetric density, is a property of powders, granules, and other "divided" solids, especially used in reference to mineral components, chemical substances, ingredients, foodstuff, or any other masses of corpuscular or particulate matter. The dry bulk density (DBD) is determined as dry mass of a rock (i.e. Density and porosity are fundamental and important physical properties of rocks in various geological problems, and affect the other physical properties. Experimental study of the use of steel slag as a geotechnical material, On the Coral Limestone from Tokunoshima and Okierabushima, An investigation of the compressibility of sandy soil under impact-wave loading. isotherms. About | The peak friction angles of aged BOF slag (with minus 9.5 mm gradation) samples prepared at 90% relative compaction were equal to 47.3°, 45.2°, and 43.5° for drained triaxial compression tests performed at isotropic consolidation stresses of 50, 110, and 200 kPa, respectively. Long-term swelling tests were performed for compacted mixtures of both fresh and aged BOF slag and 10% Class-C fly ash (by weight) and for compacted mixtures of fresh EAF(L) slag and 5, 10, and 20% Class-C fly ash (by weight). lb can serve as a time scan of the motion of the soil that would occur with instantaneous detonation of the entire explosive layer (the s coordinate along the horizontal axis corresponds to the time t = s For investigation of the compressibility of bulk sandy soil with natural moisture content (about 4%) and density P00 = 1.54 g/cm s under impact-wave loading in the region of lower pressures, piezoelectric pressure sensors (PPS) were used [7, 8]. The geotechnical test showed that the soils in the area are predominantly Sandy Silty Clay, Clay and Coarse Sand, fine aggregates, probably sandfill. Sedimentary rock - Fabric The fabric of a sedimentary rock controls the rock s porosity and permeability and therefore its ability to hold and/or transmit fluids . Public: This dataset is intended for public access and use. Bulk density of a composite material (rock) consisting of n components is (4.2) ρ = ∑ i = 1 n ρ i ⋅ V i where ρi is the density and Vi is the volume fraction of component i. The number of porosity determinations per item ranges from 1 to 2,109. Therefore, measuring bulk density of a sample can provide an estimate of porosity if the constituants of the bulk sample are known. One cubic from the borrow does not translate to one cubic dump. The first part of the paper overviews the methods most commonly used for measuring the dry bulk density (DBD) of rocks for the estimation of mineral resources. The obtained data reveal the positive effect of blast furnace slag addition on the properties of studied concrete. The normal pressure in the soil 2 was measured by pressure sensors 3 placed at distances of x = i0, 20, 30, and 40 mm from the plane of the explosive charge i (a square plate 2 mm thick with a side of 25 cm). The critical-state friction angle of fresh EAF(L) slag was equal to approximately 40.6° according to large-scale direct shear tests results. Phosphate Acid Fertilizer 60 PhosphateMica, Rock, Broken 75-85 Phosphate Rock, Pulverized 60 Phosphate Sand 90-100 Phosphate, Triple Super, Ground 50-55 Phosphate Disodiurn (See Sodium Phosphate)-Plaster of Paris (See Gypsum)-Polyethylene Resin, Pellets 30-35 Polystyrene, Beads 40 During placement in the cuvette, the soil (witha bulk density of 1.54 g/cm 3) was levelled and tamped to a density of 1.68 g/cm 3. Of the four methods tested the wax-immersion method was determined to be the most accurate method. We propose that the mechanism through which the clay cement (and other interlocking grain bonds) was eased apart was through freeze–thaw processes associated with the summer ‘active layer development (ALD)’ during the last glacial activity in the UK. The speed of motion of the load along the soil layer is equal to the speed of detonation of the explosive (DBB = 7.85 km/sec), which significantly exceeds the speeds of propagation of the IW and the discharge wave in the soil; therefore, it may be assumed with some precision that the x-ray given in Fig. those materials with a specific gravity more than 1. The explosive charge was detonated simultaneously along the entire left end, while the x-ray pictures were taken every 33 and 9 ~sec after detonation; the x-ray photograph is shown in Fig. 661, DETERMINATION OF BULK DENSITY OF ROCK CORE USING STANDARD INDUSTRY METHODS, Kacy Mackenzey Crawford, Michigan Technological University, Master of Science in Civil Engineering (MS), Department of Civil and Environmental Engineering. (ii) The bulk density must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. For a porous rock, the volume fraction for the pore space is given by the total porosity φ and Equation (4.2) is … This density is known as the saturated-surface-dry density. Get Price Despite of an obvious importance of the density for accurate estimation of resources and reserves it is often overlooked and receives significantly less attention then assayed metal grades. The bulk density of a rock is ρ B = W G /V B, where W G is the weight of grains (sedimentary rocks) or crystals (igneous and metamorphic rocks) and natural cements, if any, and V B is the total volume of the grains or crystals plus the void (pore) space.… The stiff coral limestone including a slight amount of impurities calcined at 950°C is of good results, but the porous coral limestone including a large amount of impurities, i.e. This Bulk Density Chart contains a searchable database of nearly 1000 products with dry powder or granular characteristics. Testing revealed that ASTM C127-07 does not accurately represent the particle density of the material due to the large surface pores where, mainly in the blast slag samples. The results of this research showed that both mixtures of BOF slag and Class-C fly ash and mixtures of EAF(L) slag and Class-C fly ash can be utilized effectively in subgrade applications.^. > To find a specific product, enter the name (or part of the name) of the product you are looking for in the “Live Material Search”. 10. 2. BULK MATERIAL DENSITY TABLE. Analyses reveal that the Abakaliki Pyroclastics are not completely satisfactory as concrete aggregates source, despite their origin, texture, strength and economic availability. the pyroclastics would likely perform marginally well as concrete aggregates, especially in heavy Portland cement concrete and bituminous concrete. The results of the findings show that as the partial replacement of cement with ground glass increases from 10% to 40%, the tensile strength of specimens for all curing periods of 3 to 56 days decreases. The mixtures were prepared by adding 5 and 10% Class-C fly ash (by weight) to aged BOF slag and 5, 10, and 20% Class-C fly ash (by weight) to fresh EAF(L) slag. approximately 9% to 30% wet basis. This is due to appreciably high values of natural moisture content, low bulk density, relative density and specific gravity, which suggests low durability, high voids and less aggregate absorption in concrete and bitumen mixes. These methods were the caliper method, instantaneous water immersion method, wax immersion method, and wax-shrink wrap immersion. The critical-state friction angle of fresh and aged BOF slags was in the 45.3°-48.1° range according to large-scale direct shear test results. As 1000kg of pure water = 1 cubic metre, those materials under 1000kg/cu.m will float; more dense will sink ie. Below are presented some results of measurements of the compressibility of broken sandy soil of natural mositure content in transient and reflected IW, generated by the detonation of a flat layer of explosive, in the pressure range from 0.07 to 7.84 GPa. The swell factor expressed in percentage is the amount of volume increase from bank volume (undisturbed, in place state) to loose volume (disturbed, excavated state) of the material due to voids (air pockets) added to the material after excavation. Samples of fresh and aged basic-oxygen-furnace (BOF) slag and of fresh electric-arc-furnace-ladle [EAF(L)] slag were characterized through a series of laboratory tests (specific gravity, grain-size analysis, X-ray diffraction, compaction, maximum and minimum density, large-scale direct shear, consolidated drained triaxial, and swelling tests). The specific gravity of the GG was found to be 3.67 and the bulk density was 1275kg/m³. Most of the data are from the more accessible American, British, German, and Swiss literature. Moisture content will have a marked influence. were conducted on these samples.Slaking test and sedimentation test were also made on these coral limestones calcined at 950°-1100°C. The rocks are rated as moderate to high strength material on the basis of their unconfined compressive strength values, but are very likely to have low durability as buttressed by poor sulphate soundness test results, probably due to high amount of weak minerals. Four different methods commonly used in the aggregate and mining industries to determine the bulk density of materials were examined. The research investigated four common techniques used to measuring the bulk density of materials. Sixty (60) cylinders of 150mm diameter and 300mm high were cast, three (3) samples for each of the percentage replacement groups of 0%, 10%, 20%, 30% and 40% corresponding to the curing ages of 3, 7, 28 and 56 days for each test. The maximum size of the soil particles was d = 0.5 mm. Squash bugs are among the most common garden bugs which Rock Phosphate Bulk Density are responsible for attacking and destroying squash plants.They also attack the “cucurbits” such as the cucumber and the bougainvillea fertilizer pumpkin. However, if you have values that you believe are more accurate, use them for your calculations, and please send me an e-mail to let me know what your values are. The bulk densities are given for sedimentary rocks as well as soils, because sedimentary rocks typically have variable porosity. This difficulty comes from many sources such as irregular volume, porosity, moisture content of the material, permeability of the material and the lack of a clear definition of density itself. (4) The effect of calcining temperature on the slaking velocity of calcined ore is governed by the chemical and physical properties of the original rocks. Most are from BOCA or ASAE tables. produced in phosphatic fertilizer plants Phosphoric acid Plant foods. The addition of blast furnace slag leads to lower total open porosity of studied material what takes effect on the deceleration of chloride transport. This is strong evidence that freeze–thaw and ‘ALD’ processes are major factors in determining the thickness of SR across this outcrop. The average value of CaCO3 content of Okierabushima are is 94.73%, but the coral limestone from Tokunoshima is of poor quality with a purity of CaCO3 89.50%. Therefore, measurements of density and porosity of rock samples are important investigation items in both geo-science and geo-engineering areas. 2.50 Rock Type The dry bulk density (DBD) is determined as dry mass of a rock (i.e. Except where noted, this work is licensed under a Creative Commons Attribution 4.0 International License It proved to be the case that ul/u = 1.36. Get Price; Bulk Density Chart - Anval. lb. The normal pressure in the IW reflected from a steel plate 4 of thickness 4 cm was measured by a pressure sensor placed in the plate flush with its surface.

Despite of … As moisture increased, length increased linearly from 6.42 to 7.20 mm (B) and 8.71 to 9.15 mm (J), width increased from 2.90 to 3.49 mm (B) and 4.12 to 4.43 mm (J), thickness from 2.94 to 3.20 mm (B) and 3.29 to 3.63 mm (J), and area from 14.13 to 19.44 mm2 (B) and 27.75 to 31.25 mm2 (J). Additionally, the dynamic repose angle and one thousand-kernel weight increased linearly from 46.3° to 54.0° (B) and 46.3° to 54.5° (J) and from 32.26 to 41.51 g (B) and 45.30 to 63.07 g (J), respectively, as the moisture content increased. The total volume includes … SiO2, Al2O3, Fe2O3 and MgO, has a slow slaking velocity at this calcination temperature. From above the explosive charge was covered with a layer of the same soil to a thickness of 5 cm. Most of the major rock-forming minerals in the Earth's crust, like quartz, feldspar, and calcite, have very similar densities (around 2.6 to 3.0 g/cm 3). Thirty-six (36) beams of 100x100x500mm were also cast for flexural strength test, three (3) samples for each of the percentage replacement groups of 0%, 20% and 40% corresponding to the curing ages of 3, 7, 28 and 56 days. > The physical properties such as moisture content, bulk density and specific gravity of the ground glass (GG) were determined. Current Arctic datasets of air and ground temperatures were obtained to provide reasonable starting conditions for input variables. (3) It seems that the coral limestones located at higher terraces in Tokunoshima and Okierabushima have larger crystal size, larger thermal expansivity and more rapid thermal decomposition velocity than those of the coral limestones located at lower terraces, respectively. The research also investigated the issue of moisture saturation into the rock core. Several measurement techniques of the density and porosity are available and being applied currently. Dissertations, Master's Theses and Master's Reports This research investigated a common industry method used to determine the bulk density of rock core samples typically encountered in the mining industry. Following results were obtained. Scanning electron microscopy (SEM) analysis of core samples suggested that the non-durable rock or saprolite had greater cementation of clay particles. This was due to the liquid waxes ability to closely mold into the surface pore of the sample which gives the most accurate estimate of the volume of the sample. Journal of Applied Mechanics and Technical Physics. The bulk density of a rock is ρ B = W G /V B, where W G is the weight of grains (sedimentary rocks) or crystals (igneous and metamorphic rocks) and natural cements, if any, and V B is the total volume of the grains or crystals plus the void (pore) space. Crawford, Kacy Mackenzey, "DETERMINATION OF BULK DENSITY OF ROCK CORE USING STANDARD INDUSTRY METHODS", Master's report, Michigan Technological University, 2013. This is an important parameter in the portioning of concrete mixes. > The result of applying Eq. Hence, caution is required when they are used in concrete projects. Eq. Geotechnical engineering applications can be used for this purpose.^ The main objectives of this research were to determine the geotechnical engineering properties of two types of steel slag generated from different steelmaking operations and to assess their potential use in subgrade stabilization and embankment construction. Bulking or swell factors for some materials: 1 kg/m3 = 0.0624 lb/ft3 The main problem in determining the bulk density of rock core is obtaining an accurate estimate of the rock core’s total volume. Compacted mixtures of both Class-C fly ash and BOF slag and of Class-C fly ash and EAF(L) slag showed excellent strength gain with time. S. V. Rzhevskaya and V. A.
