Pozzolans and the Pozzolanic Reaction

摘要: The most often used mineral admixture in the modern concrete industry is pozzolan. A pozzolan, and there are many of them, defined as “siliceous or siliceous aluminous materials which themselves possess little no cementitious value but will, finely divided form presence moisture, chemically react with calcium hydroxide at ordinary temperatures to compounds possessing properties” [1].
