Modulus of Subgrade Reaction - Pavement Interactive

The modulus of subgrade reaction (k) is used as a primary input for rigid pavement design. It estimates the support of the layers below a rigid pavement surface course (the PCC slab). The k-value can be determined by field tests or by correlation with other tests. There is no direct laboratory procedure for determining k-value.

Density of Cement, Sand and Aggregate, Bulk Density of Aggregate

The cement is mixed with fine aggregate to have mortar for plaster and masonry, and with sand and coarse aggregate to give concrete. As I said, earlier density is the material's mass per unit volume. Since we measure mass in kg or lb and volume in litre or cubic meter or cubic feet, hence density is stated in Kg/m3 or lb/ft3.

How Thick Does Concrete Need to Be to Hold Up Weight?

Concrete has inherent compressive strength -- resistance to forces pushing on it. Concrete mixes are designed to a specified compressive strength, expressed as pounds per square inch (psi). Concrete for works, such as driveways or floors, is typically in the range of 1,800 psi to 4,000 psi for compressive strength.
