Book excerpt: This study therefore investigated and improved cementitious properties of pozzolan blended with calcium hydroxide, gypsum and cement in order to extend its use from low strength mortars to concrete works which can be used for low to medium rise structural applications. Characterization, strength tests and durability tests were performed on pozzolan mixtures under laboratory conditions and the effects of adding gypsum to pozzolan and calcium hydroxide mixtures on the compressive strength and durability of cured concrete specimens were investigated.
