Reactions with aluminous pozzolanic materials will be briefly considered below. The dominate hydration product of Portland cement is C-S-H (Calcium Silicate Hydrate). If it is assumed that the reaction of Pozzolan

Pozzolan

May 01, 2020· 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 compounds having cementitious properties. It is therefore classified as cementitious material.
