Concrete weight calculator volume vs. mass of concrete

2021-7-28  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.

EARLY HISTORY OF MASS CONCRETE

2016-3-24  The cement content in Hoover Dam was exactly four bags per cubic yard, or 376 pounds. The cement was much coarser than present-day cement and more water was used in the concrete than would be used today. Both of these conditions made it necessary to use more cement to obtain the desired strength. Remember that Hoover was constructed

Thermal mass of concrete

Concrete has a high thermal mass with properties similar to brick and stone. It is possible to absorb heat from the atmosphere in warm weather and release it during cooler periods, e.g. overnight. This is known as the ‘thermal flywheel’ effect. In a passive concrete design the cooling capacity of concrete can be up to 25W/m 2 and with an ...
