FFECT OF POZOOLANIC MATERIALS ON COMPRESSIVE STRENGTH OF GEOPOLYMER CONCRETE

Abstract

The development that has occurred in industries and technologies after the Industrial Renaissance and beyond has led to consume a large amount of raw materials. The huge consumption of these materials is hard to be compensated. Therefore, it is necessary to find materials that can be recycled and environmentally friendly materials. Hence, the idea of sustainability, which states, the ability to meet our current needs without compromising the ability of future generation to meet theirs. It has become an urgent to produce materials that called environmentally friendly or sustainable materials.In the field of civil engineering, an important role has been played in producing of environmentally friendly concrete by using pozollanic materials. Using environmentally friendly concrete instead of traditional concrete can participate in reducing the effect of global warming. In this research, local materials like metakaolin and pozollanic materials such as, fly ash and grand granulated blast furnace slag GGBFS were used in the production of an environmentally friendly concrete which they are called Geopolymer concrete. The effect of pozzolanic material type and mixing ratios on compressive strength at 7, 28 and 60 days were studied.
