Concrete weight calculator | volume vs. weight of concrete

The weight of concrete can vary slightly depending on the mix type. The most typical value widely used is 150 lb/ft^3 for the most common/ordinary concrete strength at ~ 4,000 psi = 4000 lbf / (sq in). The aggregate used, strength of concrete and how thin or semi dry the concrete is prepared are the aspects for concrete weight.
