摘要

The current study aims to enhance the utility of amplifying industrial wastes such as Ground granulated blast furnace slag (GGBS), Silica fume (SF), and carbide slag (CS), which creates both disposal and environmental benefits. For this purpose, the basic characterization, including the physicochemical properties of the materials adopted, was determined to assess their suitability. Following this, the mechanical properties, such as compressive, split tensile, and flexural strength, were determined by varying the GGBS, SF, and CS contents as a function of curing periods. The microlevel properties were also determined by resorting to X-ray diffraction (XRD) and scanning electron microscope (SEM) analysis to understand the changes with the inclusion of SF, GGBS, and CS. The test results reveal that the strength characteristics are enhanced with the inclusion of SF, GGBS, and CS contents. The maximum compressive, split tensile, and flexural strength is measured as 38.5 MPa, 4.85 MPa, and 5.78 MPa for an optimum dosage of 15% SF, 30% GGBS, 55% CS, and 10 M alkali activator. With these, compressive, split tensile, and flexural strengths are enhanced by 38%, 42%, and 40% when compared to nominal concrete. From SEM analysis, it was evident that the GPC consisted of a denser matrix and stronger interfacial transition zones in precursor-modified mixes. The geopolymer concrete prepared in the current study complies with the requirement of strength characteristics similar to the M25 grade of concrete. The same can be employed as a replacement for conventional concrete in the construction of residential buildings, which can reduce the environmental footprint.
