Assessment of the Characteristics and Durability of Sesame Husk Ash Concrete

Concrete is a widely utilized building material, which is increasing the need for cement in the building sector. The main issues compelling the researchers to develop substitute materials made mostly of agricultural waste in place of cement are the exorbitant cost of cement and environmental degradation. The goal of this study is to recycle agricultural waste ash, or sesame husk ash (SHA), to make greener concrete that is more environmentally friendly and sustainable by replacing cement. The impact of using sesame husk ash (SHA) as a partial replacement for cement on the durability and compressive strength of SHA concrete was investigated in this study. The influence of sesame husk ash (SHA) on cement paste was investigated for the addition of 0, 5, 10, 15, and 20 % SHA by weight of cement. The compressive strength and durability of concrete produced with 0 %, 5 %, 10 %, 15 %, and 20 % of SHA were investigated. Hundred (100 mm) cubes of SHA-concrete were tested for compressive strength at 3, 7, 28, and 54 days of curing, and water absorption was also investigated. The study's findings show that as the proportion of SHA content rises, so do the paste's consistency, setting times, and soundness. The strengths of SHA-concrete enhance as the curing age increases, almost at all levels of replacement, and reduce as the percentage of SHA content increases. Furthermore, the addition of SHA content increases the water absorption of concrete. It was concluded that the optimal amount of SHA to be used should be between 5% and 10% replacement in the formation of concrete.
