DURABILITY STUDY ON FLY ASH BASED GEOPOLYMER CONCRETE FOR ACIDIC ENVIRONMENT

Abstract

The production of cement is harmful to the environment. It is important to decrease the creation of Ordinary Portland Concrete. On the opposite side, the thermal power plant expends hectares of land for the dumping of fly fiery remains which is waste material. This paper concentrates on low calcium fly ash based geopolymer concrete. In the geopolymer concrete, the diverse centralization of sodium hydroxide, for example, 8, 10, 12, 14, 16, 18, and 20 molars was utilized. The sodium silicate to sodium hydroxide proportion kept up as 2.5. The eight rate convergence of sulfuric and hydrochloric acid were utilized for the corrosive assault on fly ash based geopolymer concrete. The test perform for oven and steam cured fly ash based geopolymer concrete. The streamlined level of warming utilized for various curing techniques. After the curing, the cube kept in sulfuric and hydrochloric acidic condition for up to the half year. The acidic impact assessed at once interim of 0, 45, 90, 135, 180 days. It is watched that the sulfuric corrosive is unsafe to the fly powder based geopolymer concrete as contrast with hydrochloric corrosive. The cube sample cured for oven and steam curing. The optimized degree of heating used for different curing methods. After the curing, the cube sample were kept in sulfuric and hydrochloric acidic environment for up to the six months. The acidic effect evaluated at a time interval of 0, 45, 90, 135, 180 days. It is observed that the sulfuric acid is harmful to the fly ash based geopolymer concrete as compare to hydrochloric acid.
