The goal of the current study is to determine the dissolving effect of slag in water. Five percentage values of slag were taken up for the study: 0%, 2.5%, 5%, 10%, and 20%. The study is based on two methods of mixing. The first method is the traditional mixing process, which involves addition of slag directly with other concrete proportions such as cement, sand, water, coarse

As a final conclusion, we can say that cement substitution with slag can be considered a good strategy to reduce cement consumption while alleviating the waste management problem. Promising results have been obtained for certain mixtures, where the properties of the resultant concrete are even improved compared with the reference mix.
