Performance assessment of geopolymer concrete with partial replacement of ferrochrome slag as coarse aggregate
Abstract The present research work aims to produce fly ash geopolymer concrete with ferrochrome slag as coarse aggregate. The experimental results of all the properties of ferrochrome slag based geopolymer concrete are compared to controlled geopolymer concrete and proved as most efficient, technically acceptable and environmentally compatible construction material. From compressive strength, flexural strength and split tensile test results, it is observed that ferrochrome slag based geopolymer concrete shows excellent performance than that of controlled geopolymer concrete. Further, scanning electron microscopy (SEM) Energy dispersive X ray analysis (EDX) Fourier transformed infrared spectroscopy (FTIR) and X ray diffraction (XRD) analyses are performed to study the behavior of microstructure with effect of different conditions.
