A Comparative Study on Strength Characteristics of Fiber Reinforced Geoactivator Activated Geopolymer Concrete
This paper presents the behavioural comparison of plain and fibers added geopolymer concrete (GPC) prepared by fly ash-ground granulated blast furnace slag (GGBFS) based and activated with geo activator with silica modulus (Ms) of 2.92, test specimens cured under normal temperature curing conditions. The production of carbon dioxide is approximately 8%, experimental work is done in this research to develop a field construction binder that replaces the OPC and reduces the emission of carbon dioxide (CO2), producing green and sustainable concrete. Any earth crust materials which are rich in silica (Si) and alumina, to activate the source materials combination of sodium or potassium-based activators are used by many researchers but it requires high concentration and oven heat curing at 60 °C for 24 h, to get better strength making it an uneconomical and still it is inconclusive for field construction. In this research, a single reagent alkaline-based solution, geo activator (neutral grade sodium silicate) was used to develop the fiber-reinforced GPC (FRGPC). This research work is done to understand various mechanical properties with geo activator and checked the workability before going to cast the specimens. The results of this paper are useful for construction industries and also future researchers.
