It is necessary to reduce the effect of carbon dioxide, as failure to do so will result in global warming. In this instance, researchers have begun looking for sustainable building materials. Industrial byproducts like flyash, GGBS, silica (SiO2) are used to make geopolymer concrete. To produce binders alkali liquids can be used to react with aluminate, silica and with flyash, alkali activated concrete is made by mixing binders with coarse and fine particles and forming a mixture.. In addition to this concrete sugarcane bagasse fibres is added to improve the properties of concrete. The main objective of this paper is to study the durability properties in terms of like acid attack resistance on sugarcane bagasse fibre reinforced geopolymer concrete (GPCF) of G40 equivalent M40 when it is exposed to 5% acids attack with the help of experiments. The test specimens were casted and then cured in an oven at 60°C for 24 hours after one day rest period. The test specimens were kept at room temperature for the remainder of the time. After 28 days, the specimens were immersed in acids such as HCL and H2SO4 for 15, 45, and 75 days before being tested according to codal procedures on the 15th, 45th, and 75th days, and the results were compared to controlled concrete (CC), sugarcane bagasse fibre reinforced controlled concrete (CCF), and geopolymer concrete (GPC)). From the results it is observed that CCF and GPCF showed more resistant than CC and GPC when it is subjected to acids attack.
