What Does Pozzolan Mean? Pozzolan refers to any of several silicate materials that produce cement-like materials when they react with calcium hydroxide. Pozzolans are typically used as a substitute for cement to produce concrete because they reduce the likelihood of corrosion due to sulfate attacks. Advertisement Corrosionpedia Explains Pozzolan

Glass content of natural pozzolans of volcanic origin generally varies from 50% to 97% and the rest are mostly clay minerals, quartz, and feldspars. Glassy phase in diatomaceous earths may be as low as 25%, and some may be almost totally glassy. The remainder is composed of clay minerals, quartz, and feldspars.

A pozzolan is a siliceous or siliceous and aluminous material that in itself possesses little or no cementitious value but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form …
Synthetic pozzolans are produced using local materials to provide a cementitious material that is uniform in chemistry and properties independent of the location where the materials are obtained. Two methods of production are described. One is a high temperature process in which materials are processed in a semi-molten or molten state.
