Investigation of fly ash and rice husk ash-based geopolymer concrete using nano particles

Geopolymer concrete is generally composed of alumina-silicate materials combined with alkaline solution. Geopolymer concrete plays a vital role to safeguard the environment by way of eliminating cement in concrete. The agricultural and industrial disposals include rice husk ash and flyash can be used as binding material and it is activated using alkaline solution. Concrete structures usually constitutes significant portion across the nation which include piers, dams, canals and so on. The durability property of concrete is to be addressed properly to ensure the safety of the structure. The current paper investigates the strength and durability characteristics of combined effects of rice husk ash, flyash, GGBS and nano TiO2 geopolymer concrete specimens. Incorporation of GGBS and rice husk ash enhances the concrete properties significantly. Addition of GGBS eliminates the curing of concrete under controlled environment.
