Investigating the Effect of Two-Component Cement on the Physical Characteristics of Self-Compacting Concrete and Its Carbonation Rate

In this research, there are 19 different mixtures, each of them consists of a combination of gray and 325-1, 425-1, and 525-1 cement. The samples are made by replacing 10, 20, 30, 40, and 50 percent of white cement instead of gray cement. They have been prepared in the relevant molds as described below and subjected to compressive and tensile tests, water absorption and finally carbonation, the results of which are given in the relevant tables in the fourth chapter. In general, 228 concrete samples were concreted in 7 combinations in 4 different molds, and the samples were measured after 28 days under the mentioned tests. The general results show the high compressive strength of the samples containing a high percentage of white cement, which showed completely opposite results in carbonation, but the water absorption was also lower in concrete containing white cement than gray cement.
