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.

Most lightweight aggregate is produced from materials such as clay, shale, or slate. Blast furnace slag, natural pumice, vermiculite, and perlite can be used as substitutes, however. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material.
