Understanding the Density of Concrete Aggregate Research
Lightweight concrete uses pumice, a very lightweight mineral, as aggregate. One way to determine the density of concrete is to first determine the density of the materials that go into it. Cement weighs 830 to 1,650 kilograms per cubic meter, equal to a range of 52 lbs. per cubic foot to 103 lbs. per cubic foot.
