The Pumice Store: Lightweight Concrete Aggregate

Lightweight Aggregate. PUMICE CONCRETE is composed of Portland cement, pumice stones, pumice sand, pumice powder (pozzolan), and water. Compared to standard concrete, pumice concrete offers roughly a one-third reduction in weight and four times the r-value. Proportioning, mixing and placing are done in a similar manner to that of standard concrete.

FAQs about Hess Pumice Powder and Aggregate

Take, for instance, the decorative concrete industry. Pumice is used as both a lightweight aggregate and a concrete performance super-charging pozzolan. But it’s the whiteness of Hess pumice—scoring a GE brightness of 84—that seals the deal: as the final whiteness of the concrete product or the pureness of its dyed color is critical.
