Abstract
This project focuses on the study of sustainability to the cement – less geopolymer concrete by partially replacing fly ash by GGBS and fine aggregate with rubber crumbs obtained from waste tyre. Geopolymer concrete has become more popular in recent years due to the fact that it is significantly more environmentally friendly than standard concrete. Geopolymer concrete usually includes the fly ash, fine aggregate and coarse aggregate activated by means of alkaline liquids like sodium silicate and sodium hydroxide which is effective in oven curing. For the purpose of utilizing Geopolymer concrete for the insitu applications, fly ash is partially replaced by means of Ground Granulated Blast Furnace slag which requires ambient curing conditions. Further, the rubber crumb is obtained by shredding the waste rubber tyre. By using rubber crumb in construction purpose, it reduces the exploitation of natural resources and environmental pollution. Geoploymer concrete of grade M40 with rubber crumb as a replacement of fine aggregate was studied for its strength and durability properties. In this study, the optimum mix ratio with 10% rubber crumbs paver blocks were casted. The strength and durability results of optimum mix paver block is compared with conventional geopolymer paver block.
