Pozzolan - Wikipedia
Pozzolans are a broad class of siliceous and aluminous materials which, in themselves, possess little or no cementitious value but which will, in finely divided form and in the presence of water, react chemically with calcium hydroxide (Ca(OH) 2) at ordinary temperature to form compounds possessing cementitious properties. The quantification of the capacity of a pozzolan to reactA Review On Environmental and Health Impacts Of,In a dry cement manufacturing process, dry raw mix contains less than 20% moisture by mass.
