Study of Long Term Durability Characteristics of Steel Fibre Geopolymer Concrete

The three basic needs of man are food, clothing and shelter. Civil Engineer has relevance with all basic needs of man directly or indirectly. Cement concrete is one of the most important and relatively cheap construction materials, which contain cement, coarse aggregates and fine aggregates. In developing country like India use of concrete is more which results in increasing demand as well as rates of raw material for concrete so there is need of find some alternatives to these material, now researchers has progressed a lot in developing the method of constructing shelter. Now a day’s most of the research has focused on use of the waste material in concrete according to their properties. In this study, M 20 grade of concrete was produced by replacing cement with fly ash. For this 12 cube of Geopolymer concrete with varying proportion of steel fibres and this cube were kept 90 days for chloride attack and then compressive strength and tensile strength were evaluated. The results showed that compressive strength of steel fibre Geopolymer concrete is more than conventional concrete.
