Get PriceQuestion: Before placing the concrete for the last pier of a drilled-pier foundation job, the foreman decided to add water to the ready mix truck. The inspector didn't like the looks of the watered-down concrete and took test cylinders that represented that one pier. The specifications call for a 28-day strength of 3000 psi.

Get PriceThe ACI Code provides the accepted empirical expression for modulus of elasticity:. where E c = modulus of elasticity of concrete in compression (psi) w c = unit weight of concrete (lb/ft 3) f c ′ = compressive strength of concrete (psi). This expression is valid for concretes having w c between 90 and 160 lb/ft 3.For normal-weight concrete, the unit weight w c will vary with the mix
