  • Pozzolans

    Pozzolans. Pozzolans are materials that are not themselves cementitious, but contain constituents that will combine with lime at ordinary temperatures in the presence of water to form stable insoluble hydraulic compounds. Pozzolans have been subjected to heat either naturally (volcanic earth) or artificially (crushed fired clay brick and tile).
