Abstract

The global warming is caused by emission of greenhouse gases, such as carbon dioxide, carbon monoxide into the atmosphere (Kumar & Ramujee, 2016; Bhalchandra & Bhosle, 2013). In terms of global warming, the High performance technology could significantly reduce the carbon dioxide emission into the atmosphere caused by cement industries. The present experimental studies are carried out in order to develop a relationship between compressive strength and flexural strength of hybrid fiber reinforced geopolymer concrete. In the present study, the existing relationship in IS 456:2000 was evaluated and then a similar relationship equation was developed for fiber reinforced geopolymer concrete of G40 grade Geopolymer mixes incorporated with different percentages from 0% and maximum up to 2% of hybrid fibers taken by weight of binder (Kumar & Ramujee, 2016). The results of the present experimental study have shown increase in strength properties of Hybrid Fibers Reinforced Geopolymer Concrete (HFRGPC). It was analyzed that the compressive strength and flexural Strength were related together and the 0.5 power relationship was found to be high when compared to Open Platform Communications (OPC) based concrete. Thus the alternative equations were proposed for the HFRGPC.
