Abstract

Geo-polymer concrete has gained attention of Civil engineers due to low carbon foot prints. In this study, M30 grade geo-polymer concrete is developed with fly ash, silica fume and quartz powder as source materials & Sodium Silicate and Sodium Hydroxide as an alkaline solution. Geo-polymer concrete mixes are prepared with alkaline solution to binder ratio as 0.35 by weight. The fly ash is replaced with silica fume & quartz powder in ratio of 5% and 10% to enhance mechanical properties, respectively. The concrete is cured at 60°c temperature in oven for 24 hours. The various parameters such as compressive strength, split tensile strength and workability are studied. Mechanical properties and optimum percentage of silica fume and quartz powder are investigated. In this experimental study, it is observed that presence of silica fume and quartz powder enhances the compressive strength up to 26% and split tensile strength up to 45%.
