Evaluating Concrete Strength by Replacing Coarse Aggregate with Steel Slag and Cement with Bentonite Powder

This research investigates the mechanical strength of concrete by partially replacing cement with bentonite powder and coarse aggregate with steel slag. Bentonite is used at replacement levels of 0%, 10%, 20%, and 30%, while steel slag is uniformly incorporated at 60%. To assess the performance, tests such as compressive strength, split tensile strength, and flexural strength are performed. The results demonstrate enhanced strength properties compared to traditional concrete. Prior studies on the use of bentonite and steel slag highlight their promising potential, and this experiment aims to specifically analyze the strength behavior of concrete incorporating these alternative materials.
