AN EXPERIMENTAL STUDY ON FLYASH BASED GEOPOLYMER CONCRETE

In the paper an experimental investigation was carried out to study the behaviour of geopolymer concrete. Geopolymer concrete prepared for the experimental study is based on the use of fly ash with cement and coarse aggregate with use of sodium silicate and sodium hydroxide. Results obtained from the experimental study shows that the effect of fly ash with in considered sodium silicate and sodium hydroxide results in good strength of M35 to M40 grade concrete. The strength of fly ash based geopolymer gave good results when curing time was increased. Compressive strength, split tensile strength, flexural strength were the tests considered for the proposed experimental study.
