Abstract
In today's scenario, the essential ingredients of concrete, such as cement, and fine and coarse aggregate will vanish completely in a few decades due to its overexploitation and unscaled utilization. Similarly, cement has contributed to more emissions of carbon dioxide into the atmosphere during its stage of manufacturing, and it’s become a major influencer of increasing global temperatures. Recent researchers are finding alternative sources of materials that replace fully or partially the role of conventional concrete materials. Several industrial and agricultural solid residues are under investigation to be utilised nowadays to alter the place of conventional concrete materials and to control the impact of environmental problems. In this study, the performance of structural RC elements of M35 grade was evaluated by replacing the Nano alumina in a fixed proportion of 1% with the inclusion of ground granulated blast furnace slag and Polypropylene fibre at definite proportions in place of cement as per mix design. Engineering parameters such as compression, modulus of rupture and elasticity, crack width, and rate of deflection was examined. Based on the results of experiments, it was found that the cement proportion CAG1 and CAGP4 have provided the promotable result when compared to conventional concrete and led to using these materials instead of cement has made RC elements stronger than when they were made with regular cement.
