An overview on the Influence of Pozzolanic Materials on Properties of Concrete

Abstract

Concrete is the most normally used material for construction. The worldwide production of cement has significantly increased since 1990.Production of cement results in a lot of environmental toxic waste as it involves the emission of CO2 gas. Complementary cementitious materials are finely ground solid materials that are used to replace a portion of the cement in a concrete mixture. These complementary materials may be naturally occurring, manufactured or natural waste. Various types of pozzolanic materials that improve cement properties have been used in cement industry for a long time. This paper reviews the use of pozzolanic material in concrete. A detailed literature review is carried.
