An effort is made toward the preparation of fly ash-based building blocks with varying water binder ratios in order to achieve the goal of obtaining a building block with a high strength using both conventional and non-conventional construction materials. The purpose of the experimental program is to examine the possibility of casting building blocks using fly ash, sand, cement, and gypsum in order to meet the demand for clay bricks. 230 millimeters by 120 millimeters by 120 millimeters was the dimensions of the building block specimen that was obtained. The mix proportions that were used were fly ash (40-50 percent), sand (33-43%), cement (15 percent), and gypsum (2 percent). The water-binder ratios that were used were 0.70, 0.75, and 0.80. In addition to determining the compressive strength of building blocks in comparison to clay brick, the purpose of this research was to identify the optimal mix ratio of fly ash, sand, PPC, and gypsum for standard sizes of building blocks. Specimens were examined for a period of seven, fourteen, and twenty-eight days. The research indicates that the optimal composition for fly ash, sand, cement, and gypsum building blocks was forty percent fly ash, forty-three percent sand, fifteen percent cement, and two percent gypsum.
