Experimental Investigation On Geopolymer Concrete With Partial Replacement By Sugarcane Bagasse Ash And Waste Tyre Rubber Fiber

Abstract

Countries are quickly growing these days, necessitating additional infrastructure on a daily basis for current and future growth. Cement serves a critical function in concrete, which is needed for the construction of infrastructure and the economic growth of every nation. Geopolymer technology is one of the most effective methods for the reutilization of pozzolanic waste materials. The advent of geopolymer concrete (GPC) technology has resulted in long-term growth in the building industry. We investigated the strength and durability of GPC when Flyash (FA) and Ground Granular Blast Furnace Slag (GGBFS) are substituted with Sugarcane Bagasse Ash (SCBA) and Coarse Aggregates Rubber Fiber (RF) from old tyres in this study. Retaining structures, accident barriers, and even pavement constructions may all benefit from GPC using waste tyre rubber fiber. SCBA is used in GPC at 10% and 20% concentrations. RF is added at five percent, ten percent, fifteen percent, and twenty percent. The molarity of the alkaline solution is maintained at 12M, as recommended by numerous studies. With the rise in RF %, workability has reduced. Compressive Strength has decreased as the proportion of RF in GPC has increased. RF The post-crack toughness of GPC with RF is greater than that of GPC without RF. Acid assaults are more susceptible to GPC with RF. The Split Tensile Strength of GPC has risen as the RF % has increased, while the Split Tensile Strength of SCBA has decreased as the SCBA percentage has increased. Flexural strength has decreased as the percentages of SCBA and RF have increased.
