Geopolymer Self Compacting Concrete Performance Incorporating Polyethylene Terephthalate

Abstract

For the facilitation of construction industry Ordinary Portland Cement enhancing share, ultimately contributing to rise in the global temperature. Infrastructure concern with green concrete as well as cost and service life. Thus, to counter these problems Self Compacting Geopolymer Concrete (SCGC) is gaining much attention. This research’s aims to analyse Poly-Ethylene Terephthalate fiber effect on SCGC. Ground Granulated Blast Furnace Slag (GGBFS) along with Fly Ash were utilized class F in three different proportions (40:60, 50:50 and 60:40) as binders along with alkali activators. For elasticity to hardened properties slump flow of T500 mm test, V-funnel test and L-box, as well as the mechanical properties tests were done accordingly. Results showed hardened properties enhanced with the increase of the slag quantity, The reinforced with PET fibers in different percentages (0, 0.05%, 0.1%, 0.15%, 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5%, 1% and 1.5%) by volume of the mix respectively. Fibers addition till 1% increased the compressive strength by 13% approximately, but at 1.5% addition the strength started to reduce. Hence up to 0.5% addition of PET fibers fresh properties satisfies the requirements for Self-Compacting Concrete (SCC), but 1% and 1.5% didn’t. This research sought to assess SCGC properties after PET inclusion.
