Effect of Combination of Alumina-Silica Rich Minerals with Fly Ash on Structural Behaviour of the Basalt Fibre Reinforced Geopolymer Concrete

Abstract

Cement production is one of the major C02 emitter which contributes around 8% of the world’s carbon dioxide emissions. So the Engineers are in the need of developing alternate material for cement to reduce the effect of vulnerable climatic changes in the world. This paper aims at presenting the experimental study on effect of combination of silica rich minerals with fly ash based geopolymer concrete. Fly ash was found to be successful in enhancing the performance of geopolymer concrete. The Utilization of more industrial wastes will promisingly contribute for reducing the environmental pollution. To determine the effective admixture combination with fly ash in geopolymer concrete, industrial wastes such as silica fume, GGBS, Metakaolin, palm oil fly ash were used. The concrete mixes were designed with 60 percentile of fly ash and 40 percentile of other industrial wastes to replace the cement in Geopolymer concrete. The Concrete specimens were casted and cured at different conditions namely Oven curing, Steam curing and sunlight. The Compressive, tensile and flexural strength behaviors were determined for the designed concrete mixes and the results were presented.
