Also, there is a given there that will not be needed in the problem. 2. Soil sample was collected above the water table with moisture content of 14% and a unit weight of 18 kN/m3.The wet density of a compacted soil is 18.5 kN/m3 and has 97% of its pore spaces filled with water when the moisture content is 29.5% What is the specific gravity of the soil solids? Determine the void ratio and porosity. Use unit weight of water = 9.8X kN/m3, where X is the last digit of your student number. We have weight of sample W 1. Weight of sample and wax W 2. Hence weight of wax Wwax would be W 2 minus W 1. Here volume of wax can be determined by unit weight formula as this. This is the volume of wax used to cover the soil sample. Next we take a container with overflow management attached to it.Density = Mass / Volume. Soil density is expressed in two well accepted concepts as particle density and bulk density. In the metric system, particle density can be expressed in terms of mega grams per cubic meter (Mg/m3). Thus if 1 m3 of soil solids weighs 2.6 Mg, the particle density is 2.6 Mg / m3 (since 1 Mg =1 million grams and 1 m3 =1 ...

Soil consistency is the strength with which soil materials are held together or the resistance of soils to deformation and rupture. Soil consistency is measured for wet, moist and dry soil samples. For wet soils, it is expressed as both stickiness and plasticity, as defined below.Bulk density of soil is usually determined from a core sample which is taken by driving a metal corer into the soil at the desired depth and horizon. This gives ...W 2 = weight of mould and soil in loose state W 3 = weight of mould and soil in dense state V = volume of mould We can calculate maximum and minimum dry unit weight as weight of soil in different conditions and divided by volume of mould. Now in the equation of relative density, only unknown is the dry unit weight of soil in its natural conditions. Wet Bulk Density of Soil. Written by Jerry Ratzlaff on 17 August 2020. Posted in Geotechnical Engineering. Wet bulk density of soil, abbreviated as \(Y_{sat}\), is the ratio …[00:02:50.168] Bulk density is equal to the mass of solids [00:02:52.759] over the volume total.
