Abstract

In this experimental study the fly ash and GGBS is used to make the geopolymer concrete and PET fibers were added in it with different percentage. The fly ash and ggbs based geopolymer concrete was used with equal quantity (50% fly ash and 50% ggbs) and PET fibers were used in it (volume fraction of fine aggregates/weight percentage of fine aggregates),with different percentage i.e. 2%,3%,4% to study the mechanical and durability properties. Geopolymer concrete containing PET Fibers were cured with two methods i.e Oven curing (24 hours at 600C) and ambient curing. The PET fibers dimensions was used corresponding to 45 aspect ratio 90x2 (length x breadth).The prepared samples were tested at 7 days and 28 days. The study has been done on the fresh property, compressive strength, tensile strength and flexure strength of PET fiber encapsulated geopolymer concrete. The compressive strength improved a little with the incorporation of PET fibers, tensile strength and flexural strength tests gave significant improvement over controlled specimen.
