Experimental study on partial cement replacement with horse gram pod ash in concrete Available to Purchase

Agriculture residue management has gained popularity in recent years due to the emphasis on sustainability. After harvesting, large amounts of waste are produced, which is often dumped into the environment, leading to pollution. These wastes can also be utilized in the concrete industry to help reduce the depletion of mineral resources, contributing to long-term sustainable development. Experimental tests were conducted to evaluate the effect of horse gram pod ash (HGA) as a partial replacement for cement in concrete. The results showed that the compressive strength of mixes with HGA replacement increased by 4–8%. However, the strength decreased when HGA content exceeded 8%. Despite this, the split tensile strength of the HGA8 concrete was 10.52% higher than that of the control concrete, with 8% HGA showing superior strength compared to other replacement levels. A 26.15% increase in flexural strength was observed in concrete with 8% HGA content compared to control concrete. Durability tests, including absorption, sorptivity, rapid chloride penetration, and acid resistance, indicated that the durability properties of HGA concrete mixes are comparable to conventional concrete. The study suggests that HGA has significant potential as an agricultural waste material in green concrete due to its beneficial properties and contribution to waste management.
