Summary: | Concrete is one of the most widely and world�s oldest used construction materials, due to its versatility, durability, sustainability, and economy. This study presents the way of improving normal coal bottom ash to well-graded coal bottom ash and to investigate the effects of workability, mechanical properties, and thermal properties of normal concrete when partially replaced with well-graded coal bottom ash with sand. It was observed that the workability of the concrete showed a slight increase with normal concrete containing well-graded coal bottom ash. The compressive strength of well-graded coal bottom ash achieved the designed mix design which was 40�Mpa at the ages of 3, 7, and 28�days compared to controlled concrete. The thermal conductivity of well-graded coal bottom ash concrete showed a decrease in value compared to controlled concrete. This research concluded that 80% of well-graded coal bottom ash concrete was the optimum percentage replacement which will help achieve the beneficial strength development. � 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. |
