Formulas for Lightweight Concrete - Green Home Building

2019-8-26  Q: We are trying to develop a lightweight pumice concrete here in South Texas. We tried some mix designs, but the compressive strength yielded has been low (400-500 psi). I was wondering if someone has developed a good mix design to yield an 1200-1800 psi design. We are using pumice from New Mexico and cement.

Understanding the Density of Concrete • Aggregate

2009-11-26  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.
