Nanoproperties of Fly Ash based Geopolymer Concrete with Polypropylene Fibres

Abstract

Due of its amorphous-like properties, geopolymer concrete (GPC) possesses good quasi-brittle behavior. New studies has revealed that polypropylene fibre can also be used to concrete to increase the material's strength. In the ongoing work, a novel geopolymer concrete (FGPC) that was modified with polypropylene fibres been created as a replacement to conventional cement concrete. FT-IR, XRD, SEM, and the BET adsorption-desorption isotherm model were employed to evaluate the nanoproperties of the geopolymer concrete modified with polypropylene fibre. The maximum compressive strength will be most probably present in the developed concrete. Comparing FGPC to GPC and OPC, the pore capacity of FGPC was decreased by 0.025705 cm3/g and the water absorption was decreased. The substance in FGPC's SEM picture is denser than that in OPC and GPC. The interfacial bond between the minerals and the utilization of polypropylene fibre enhance the durability of geopolymer concrete, which was additionally supported by FTIR technique. Micro - cracks on the surface of OPC and GPC reduce compressive strength while enhancing porosity and water absorption
