Abstract
A siliceous or aluminous material, which possesses a little or no cementitious value but will, in a finely divided form and in the presence of moisture, chemically react with calcium hydroxide Ca(OH)2 to form compounds possessing hydraulic cementitious properties. The great abundance of Porcelain and Marble waste powder industrial wastes in Gujarat (India) makes it the most suitable materials for cement-based applications. To enhance the use of Porcelain and Marble waste powder as a Supplementary Cementitious Material in Gujarat (India), a proper method to evaluate its pozzolanic activity is necessary. The pozzolanic reactivity of the Porcelain and Marble waste Powder was evaluated by conducting strength development tests according to ASTM C311. After 28 days, the strength activity index of the Porcelain and Marble waste powder with ordinary Portland cement exhibited very good performance and was higher than 90 %, therefore it is suitable to produce a high performance concrete.
