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.

Pumice Pozzolan: Why Specify Hess Pozz?
2021-1-28 As the preceding data indicates, concrete made from a pumice pozz/Portland cement blend can protect steel reinforcement by creating a matrix so densely packed that liquids and/or gases cannot penetrate to cause the steel to corrode. Where very high strength and superior durability are key, the addition of a Hess UltraPozz (3µ) can enhance both ...
