Effect of SiO2 on Rice Husk Ash- Slag based Geopolymer Composites

Rohit Kumar

Abstract


In the planet, cement is most adaptable, enduring, reliable, and essential material used for edifice. After water, Concrete is most widely used material on the earth. But concrete is not eco-friendly due to large carbon footprint of cement. In current work a new eco-friendly standby of cement called as Geopolymer is worked out. The use of waste material like Rice Husk Ash (RHA), Ground Granulated Blast-Furnace Slag (GGBS) etc. and polymeric binder with no use of OPC is considered. In the present work experimental investigation is performed like Compressive strength (7 and 28 days) at ambient curing condition. Effect of SiO2 on compressive strength is evaluate in present work. The variation of SiO2 (6 %, 7 %, 8 %) and Fixed value of Na2O and different combination of RHA and GGBS (variation from (10 % to 50 %, increases 10 % in each step) was used in this paper.
