Abstract
To improve the performance characteristics of both lightweight and heavyweight concrete structures, this study explores the possibility of using Coconut Shell Ash (CSA) in substitution of some of the Ordinary Portland Cement (OPC) in concrete. After 28 days of curing, compressive strength tests were performed on concrete samples. The results showed that the best compressive strength was achieved by adding 10% to 15% CSA with a water-to-cement (W/C) ratio of 0.4. The results of the study show that concrete with 10% CSA has less water absorption, which increases durability. On the other hand, it was discovered that CSA content increases lengthened setting times and reduces workability. All things considered, the study shows that CSA can function as a useful addition to concrete mixtures, supporting environmentally friendly building methods. It is advised to conduct additional research to investigate.
