Experimental Study On Geopolymer Concrete Using Fly Ash Bagasse Ash and Metakaolin with Pet Fiber

Abstract

The continuous reduction in raw resources in the construction industry has reached the alarming newlinestage such that the usage of waste by-products from various industries has become the necessity. newlineFly ash has been used in construction industry from the last decade but there is a need for more newlineexperimental studies with other material as a substitution. Polyethylene terephthalate, known as newlinePET has been widely used for developing plastic bottles. Although it has umpteenth uses, it has newlineserious issues of biodegradability. Hence, researchers are also trying to investigate the properties newlineof PET fibers as construction material. This experimental work has been done to examine the newlinefully replacement of cement in concrete with fly ash, bagasse ash and metakaolin. Total 4 mixes newlinewere prepared for this study and strength parameters were explored. Cement was replaced fully newlinewith 70% fly ash, 20% metakaolin and 10% bagasse ash. PET fibers were also added with the newlinevarying proportion of 2%, 3% and 4%. The obtained concrete mixes were tested for its newlinecompressive strength, split tensile strength and flexural strength at 7 days and 28 days. It can be newlineconcluded from the present investigation that the Geopolymer containing 3% PET fibers is more newlineeffective in strength than the other mixes. newline
