Aquablue Chemistry: Pozzolan

A pozzolan is a material which, when combined with calcium hydroxide, exhibits cementitious properties. Pozzolans are commonly used as an addition (the technical term is "cement extender") to Portland cement concrete mixtures to increase the longterm strength and other material properties of Portland cement concrete, and in some cases reduce the material cost of concrete.
