Cement and Cement Additives – Structural Guide

Mineral additives are identified as supplementary cementitious material (Pozzolana) is a finely ground siliceous material which, as such, does not possess cementitious properties itself, but react with chemically with calcium hydroxide released from the hydration of the Portland cement at normal temperature to form low solubility having cementitious properties
