Pumice is widely used to make lightweight concrete or insulative low-density breeze blocks. When used as an additive for cement, a fine-grained version of pumice called pozzolan is mixed with lime to form a light-weight, smooth, plaster-like concrete. This form of concrete was used as far back as Roman times. Roman engineers used it to build the huge dome of the Pantheon and as construction material for many aqueducts.

Pumice is made of glass. Glass forms when molten rock cools too quickly for crystals to form.
Pumice is a form of volcanic glass that is rich in silica. There are also fairly high amounts of aluminum oxide, sodium oxide, and potassium oxide. The holes or vesicles are the remnants of gas bubbles that formed when the pumice was still molten.
