Density of soil pcf
WebIntroduction The unit weight, also known as the ‘weight density’, of a soil refers to its weight per cubic metre and is typically expressed as kilonewtons per cubic metre (kN/m3), or tons per cubic metre (t/m3)1. Knowing the unit weight of a soil is particularly important for geotechnical design, as well as assessing earthworks volumes.

WebNov 30, 2013 · I have always used 120 pcf for soil. The soil over the roof must be drained, so I think considering saturating is overkill. Not to nitpick, but I find it hard to believe soil weighing 150 pcf (the density of concrete!) unless the soil is actually solid bedrock which it wouldn't be in this case.

WebIts value usually varies from 100 pcf to about 350 pcf. Soil Density (heel side): Enter the soil density for all earth (or water if applicable) above the heel of the footing. This weight is used to calculate overturning resistance forces and soil pressures using the weight of the soil block over the projecting heel of the footing.
WebOn average, 1.5 cubic feet of potting soil/ garden soil can weigh approximately 78 pounds (37.5 quarts). 1 cubic foot of potting soil/garden soil weighs 52 pounds (25 quarts), so 1.5 cubic feet of potting soil weighs = 1.5×52 = 78 pounds (37.5 quarts). Thus, 1.5 cubic feet of potting soil weighs approximately 78 pounds. WebApr 3, 2024 · The PCF was characterized in terms of surface curing test, temperature and freeze-thaw aging property, water and wind erosion resistance, and remediation soil acidity and alkalinity property, which indicates that PCF can improve loess slope fixation and stability by physical and chemical effects.
