Development of Environmental-Friendly Geopolymer Concrete Using Incinerated Biomedical Waste Ash
To minimize the environmental pollution, a research was performed to evaluate the influence of utilizing Incinerated Biomedical Waste Ash (IBWA) for Ground Granulated Blast Furnace Slag (GGBS) in geopolymer concrete. In geopolymer concrete, the IBWA is partly replaced for GGBS by 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50%, respectively. The primary objective of this research is to analyse the fresh and mechanical characteristics of geopolymer concrete combined with GGBS and IBWA. The findings were compared between groups that did not include any IBWA and material containing IBWA content. Results indicated that the 30% IBWA replacement level provided the greatest compressive strength at seven as well as twenty-eight days, with 35.3 N/mm2 and 48.5 N/mm2, respectively. Addition of IBWA resulted in unfavourable effects when the content was higher than the recommended 30%. The results of the microstructure investigation also suggest a compact and dense geopolymer concrete micrograph at 30% IBWA, which may be attributed to the coexistence of geopolymerization products with additional calcium-based hydration products, according to the researchers. After the testing was completed, it was revealed that the presence of IBWA might be partly substituted as a raw material for geopolymer concrete, which would result in a cost reduction for the product. There is a possibility that this study will impact the use of hazardous IBWA as a construction material.
