Abstract
Experimental Study on Geopolymer Concrete with PET Fiber
Highlights
1.1 GEO-POLYMER CONCRETE Geopolymer was invented by Joseph Daidovits in 1978
Conventional concrete’s similar ingredients are used in Geopolymer concrete except that the cement is fully replaced by by-products of industries such as Ground-Granulated Blast-Furnace Slag (GGBS) and flue ash
Geopolymer concrete is a more environmentally sustainable product as it uses Fly ash and GGBS which helps in reducing carbon emissions by some 40 % to 80 % without affecting the structural properties of conventional concrete
Summary
Concrete is the most used material which required large quantities of Portland Cement. Geopolymer concrete is an ecofriendly and innovative construction material which is a possible alternative to Portland cement concrete. Geopolymer concrete consists of basic waste material such as fly ash, GGBS and alkaline activators. PET fiber (0.25 & 0.5% of weight of cube) is used mainly for two reasons one is that, it provides great flexibility which reduces the causes of crack. Another is, plastic bottle which is a main source of PET fiber are being disposed in huge quantity, in oceans and land.
