Mathematical Prediction on the strength and behaviour of structural member by incorporating Incinerated Bio-Medical Waste Ash in Ground Granulated Blast Furnace Slag based Geopolymer Concrete

Abstract

Concrete seems to be the more commonly used construction substance throughout the entire globe as well as its usage have been expanded over the last decade because the demand for building works has increased. Geopolymer concrete (GPC) is one of the technologies that may be used to replace traditional concrete. Geopolymer concrete is an inorganic alumino-silicate polymer made mostly of silicon, aluminum, and by-product materials such as Fly Ash (FA), Ground Granulated Blast Slag (GGBS), and other by-product materials. While the key motives for utilizing GPC is technical and economic advantages, the avoidance of environmental pollution by appropriate waste management has become a concern. The primary goal of this research is to see how Incinerated Bio-Medical Waste Ash (IBWA) affects the mechanical and flexural activity of GPC. In this report, IBWA is substituted for GGBS in various percentages (0, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50%). The inclusion of IBWA converts the substance from brittle to ductile, resulting in substantial improvements in tensile stress, tensile strain, toughness, and energy absorption capacities. The samples was held constant at ambient temperature throughout the curing phase. On concrete specimens, the mechanical properties of concrete, including the compressive strength of the cube, the split tensile strength and the bending strength were inspected. The experimental findings indicate that introducing IBWA to GPC enhances the mechanical behaviour of the material as well as the load carrying capability of the beams.
