Abstract

In India, a significant amount of industrial and agricultural by-products such as fly ash (FA), rice husk ash (RHA), and calcium carbide residue (CCR) are generated, posing serious environmental challenges due to their disposal. To address this issue, it is essential to focus on the sustainable utilization of these by-products in concrete, particularly for infrastructure development. Cement, a primary component of concrete, contributes substantially to CO emissions during its production. The incorporation of highly reactive pozzolanic materials like RHA and CCR as partial cement replacements can enhance both the strength and durability of concrete while mitigating environmental impacts. India, being the second-largest producer of rice globally, has abundant availability of RHA. In this experimental study, cement was partially replaced with a combination of CCR and RHA at varying proportions—5%, 10%, 15%, 20%, and 25%. The concrete was evaluated for its fresh, hardened, and durability properties. The results revealed a decrease in workability with increasing replacement levels. However, the compressive strength improved significantly, with MIX5 exhibiting a 34.7% increase, and flexural strength is showing a 15.11% improvement. MIX15 demonstrated optimal mechanical performance compared to the control mix. Ultrasonic pulse velocity (UPV) tests indicated excellent quality for MIX15. Additionally, water absorption was highest in the control mix and progressively decreased with higher replacement percentages, also resulting in a reduction in concrete density. The cost analysis further showed that the use of CCR and RHA as partial cement replacements led to a reduction in overall concrete cost.
