Abstract

This work presents the experimental results of investigation carried out on basalt fibre reinforced geopolymer concrete. The class F fly ash based geopolymer concrete was considered for this study and m-sand has been used as fine aggregate. Sodium based alkali activator solution of 10 molality was used in geopolymer. Totally six design mixes were arrived by varying the volume fraction of basalt fibre from (0 to 1%), in addition with conventional concrete. Mechanical and durability test were conducted for all the six trials. The Geopolymer concrete with 0.5% of basalt fibre shows 19.6% increment in compression and the mix with 0.75% express 73.2% and 70.4% increases in tensile and flexure respectively, when compare with conventional concrete. The mix 0.5% shows appreciable performance in durability properties.
