Abstract

This paper reports the results of an experimental program performed to study the effect of incorporation of sugarcane bagasse ash (SCBA) in Ground granulated blast furnace slag (GGBS) based geopolymer composites by performing various destructive and non-destructive tests. GGBS was replaced by SCBA in dosages of 5%, 10%, 15% and 20% by weight and activated by a solution of sodium hydroxide and sodium silicate. Some of the test performed during the experimental investigation were compressive strength, water absorption, bulk density, rebound hammer test, ultrasonic pulse velocity etc. It is observed that compressive strength and bulk density decreases with increase in the dosage of SCBA. The results of the present study indicates suitability of replacing SCBA in the GGBS based geopolymer composites.
