Study on Properties of Geopolymer Concrete using Hybrid Fibres

Abstract

Due to the ongoing loss of the ozone layer and the issue of global warming, the building industry has recently become increasingly cognizant of the importance of employing more environmentally friendly construction materials. Geopolymer concrete (GPC) has started to draw considerable interest from scholars, researchers, and construction practitioners because of its benefits in replacing cement with by-product waste and reducing greenhouse gas emissions during production. It also outperforms traditional concrete in terms of mechanical qualities and endurance. Despite its benefits, GPC is only used in a limited number of applications.This paper describes the various proportions of fly ash (100%, 90%, 85%, 80%) and bagasse ash (10%, 15%, 20%) based geo-polymer concrete. For the making of concrete, fly ash having low-calcium (Class F) is substituted for Ordinary Portland cement (OPC)as the raw material. According to earlier research, adding bagasse ash to Geopolymer concrete reduces its strength by more than 10%. The effects of strength and durability parameters were studied using silica fume (5%) and hybrid fibres (1%), and the findings revealed that GPC has increased durability and strength with the addition of silica fume and hybrid fibres. This GPC has mechanical and durability properties equivalent to OPC concrete. GPC is not only good for the environment, but it also has outstanding mechanical properties. In the future, it might be a very useful material.
