Abstract/Summary
Cement remains to be the most expensive raw material in the production of concrete. Unfortunately, it is also not an eco-friendly material as it contributes to 5% of all global greenhouse gas emission produced from factories and fossil fuels (Nogrady, 2016). In order to reduce the rising cost and environmental impact of concrete in the construction industry, it is crucial to reduce the usage of cement. A feasible way of diminishing the use of concrete is to partially replace cement with coconut shell ash (CSA) as a natural pozzolan. To ensure this method is viable in the field, this paper investigates the strength and durability properties of the partially replaced concrete. The durability properties that will be examined are sorptivity and sulfate attack will also be investigated using a scanning electron microscope (SEM). Furthermore, the optimum replacement of cement is 1% similarly to previous studies. The difference between the conventional concrete and 10% CSA is negligible according to the statistical test. Therefore, CSA is a feasible materal as an alternative to cement.
