Comparative Study on Fly Ash Based AAM Concrete with GGBS, Rice Husk Ash and Sugarcane Bagasse Ash

Abstract

AbstractOne of the main staples in the construction industry is Portland cement-based concrete, which currently contributes to 8% of global CO2 emissions during cement production. In this respect, the geopolymer technology shows considerable promise for application in the concrete industry as an alternative binder to Portland cement. Still, there has not been a significant shift away from the use of Portland Cement due to the demand for additional necessary precautions and the requirement of high temperature to bring about rapid strength gain. The mechanical and durability properties of class F fly-ash (FA), based Alkali Activated Concrete (AAM) with varying percentages of Ground Granulated Blast Furnace Slag (GGBS), Rice Husk Ash (RHA), and Sugarcane Bagasse Ash (SCBA) cured at ambient weather conditions are discussed. The results of the tests further indicate the possibility of using ambient cured AAM Concretes for construction purposes.KeywordsFly ashGround Granulated Blast Furnace Slag (GGBS)Geopolymer Concrete (GPC)Rice Husk Ash (RHA)Sugarcane Bagasse Ash (SCBA)Agricultural wasteSustainable concreteConcreteAlternative construction materials
