Sink your hand down into a pile of rich, organic soil, and you can feel the moisture in it. Moisture in soil holds it together and is a primary factor in determining the average weight of a cubic yard of soil, no matter what components the soil is made of.[...]

If the total combined quantity of the listed items is less than 10,000 square yards (8000 m 2), ensure that the coarse aggregate is one of the following size: No. 7, 78, 8, 57, or 67. Where No. 7, 78, or 8 size is selected, test the coarse aggregate according to 703.02.[...]

Equivalent dry unit weight is determined based on the moisture content and the unit weight of compacted soil. A curve of dry unit weight versus moisture content is plotted (Figure 5-4) and the maximum ordinate on this curve is referred to as the maximum dry unit weight ((γ d) max).[...]

Jul 30, 2012· After that, weight the aggregate mass that is inside the container and divide it by the volume of container. This will give you the bulk density of the loose aggregates. Compacted Bulk Density. Compacted bulk density can be determined by filling the container in three layers and tamped each layer with a 16mm diameter rounded nosed rod.[...]

PDF | Laboratory determination of compaction properties namely the maximum dry density and optimum moisture content is both time consuming and costly. Therefore, it is …[...]

Jun 09, 2005· For example, the weight of poured in place concrete, with reinforcement, is only 150 lb/ft^3. There is no way that compacted base weighs more than that. You're going way off on a tangent using some inappropriate information and extrapolating it to fit. I'm guessing compacted AB weighs no more than 120 pcf.[...]

One cubic meter of soil weighs between 1.2 and 1.7 metric tonnes, or between 1,200 and 1,700 kilograms. These metric figures convert to between 2,645 and 3,747 pounds, or between 2.6 tons and 3.7 tons, per cubic meter. Loose topsoil is lighter, and compacted topsoil is heavier. Moisture content also affects density and weight of soil.[...]

Mixed Trash (Separated into 'Wet Waste' and also the more 'Typical Mixed Waste').. Wet Waste is associated more with Food Prep, Food Service and/or Restaurant type facilities where the percentage of wet waste is higher than normal (Of course, the degree of how wet the waste is depends upon the overall amount of other trash that is being mixed in with the wet waste which helps to ...[...]

Use this calculator to estimate the quantity of Construction Aggregates needed for your particular job, based on width, length, thickness, and product density.[...]

The soil type - that is, grain-size distributions, shape of the soil grains, specific gravity of soil solids, and amount and type of clay minerals, present - has a great influence on the maximum dry unit weight and optimum moisture content. It also has a great influence on how the materials should be compacted …[...]

Density of Clay, compacted lb ft3 = 108.9992192076 lb/ft³ See density of Clay, compacted in hundreds of units of density measurement grouped by weight . Clay, compacted density values, grouped by weight and shown as value of density, unit of density[...]

To assess the degree of compaction it is important to use the dry unit weight, γdry, because we are interested in the weight of solid soil particles in a given volume, not the amount of solid, air and water in a given volume (which is the bulk unit weight).[...]

Jul 24, 2009· Strictly speaking, unit weight has units of force/(length^3). Therefore, lb/ft^3 or, kN/m^3. Unit mass would be kg/m^3 or slugs/ft^3. Calculation of static forces and stresses is often easier with unit weight, since you don't need to multiply by 32.2 or 9.81.[...]

Unit weight of a soil mass is the ratio of the total weight of soil to the total volume of soil. Unit Weight, g, is usually determined in the laboratory by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring.Measuring unit weight of soil in the field may consist of a sand cone test, rubber balloon or nuclear densiometer.[...]

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft[...]

1.1 This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.[...]

Compaction is a process that brings about an increase in soil density or unit weight, accompanied by a decrease in air volume.There is usually no change in water content.The degree of compaction is measured by dry unit weight and depends on the water content and compactive effort (weight of hammer, number of impacts, weight of roller, number of passes).[...]

Because a wide range of particles are needed in order to fill all available voids, well-graded soils tend to compact better than poorly graded soils. The degree of compaction of a soil can be measured by its dry unit weight, γ d. When water is added to the soil, it functions as a softening agent on the soil particles, causing them to slide ...[...]

Soil unit weight, as referred to as Specific weight, is the weight per unit volume of soil. It may refer to - Wet unit weight: Unit weight of the soil when the pore are fully or partially filled with water. - Dry unit weight: Unit weight of the soil the pores are filled only with air without any water. Gamma_d = Gamma / …[...]
