Our present building materials' compressive strength and thermal insulation performance must be substantially improved due to stricter energy standards. In this study, we looked into ways to enhance cement bricks' performance in terms of compressive strength. Expanded perlite, which is normally a synthetic addition based on SiO2 and Al2O3, was used as an additive in this study. To create test samples, expanded perlite that ranged in weight percentage from 3 to 5 percent was blended into cement masses. The cement masses had a 25 weight percent moisture content.
