A Study on the Strength Properties of Concrete Using Coconut Shell as Partial Replacement of Coarse Aggregate
This study investigates the strength properties of concrete that uses coconut shell as a partial replacement of coarse aggregate. Coconut shells are agricultural waste products that are readily available in tropical regions. By burning coconut shells, toxic gases such as methane and carbon-di-oxide are released into the atmosphere. The utilization of coconut shells as coarse aggregate may reduce construction materials cost and save the dumping spaces and reduce carbon emission. In this study, different percentages of coconut shell aggregates (CSA) of 2%,5%,8%,10%,12%,15%, and 20% of the weight were used to partially replace coarse aggregates in concrete. A total number of 144 cubes of concrete specimens with size (100 mm × 100 mm × 100 mm) were made with concrete mix proportion of 1:2:4 and the water-cement ratio of 0.50. The mechanical properties of the samples, including compressive strength and tensile strength were evaluated at 7, 28 and 56 days. The results show that using coconut shell aggregates in concrete can result in a slight decrease in compressive strength. From the test results, it is also seen that around 75% strength of conventional concrete can be achieved up to 8% replacement of level of coarse aggregate with coconut shell chips. The findings of this study suggest that coconut shell aggregates can be used as a partial replacement for coarse aggregates in concrete production, which can lead to a more sustainable and eco-friendly construction industry.
