The current trends in construction materials resources towards a more sustainable development environment are regenerate the industry's waste to become by-product waste as partial replacement purposes. Among these efforts is the utilization of fly ash as a partial replacement of cement in concrete work that is more eco-friendly and creates significant environmental benefits. This paper presents some experimental results and discusses fly ash as a partial replacement in producing brick aggregate concrete. Clay bricks were crushed to produce brick aggregate and replace 50 % of the natural coarse aggregate in producing concrete. The crushed brick aggregate's physical and mechanical properties such as water absorption, density, aggregate impact value (AIV), and aggregate crushing value (ACV) were determined. There are five series of concrete mixtures with 50% brick aggregate were prepared and tested. The concrete mixtures were partially replaced with fly ash ranging from 0% to 30%. A total of 45 cube specimens with the size of 100 x 100 x100 mm were prepared and tested for compressive strength at the age of 10, 28, and 90 days while ten-cylinder specimens with the size 150mm x 300mm were prepared and tested for splitting tensile strength at the age of 28 days. The results indicated that the concrete mix with partial replacement of fly ash gained higher compressive strength during age 28 days but less than control specimens at 90. The splitting tensile strength of concrete containing fly ash overall was lower than the control mix. As expected, the water absorption for the concrete mixture containing fly ash was decreasing. The optimum percentage used of fly ash as a partial replacement for cement for brick aggregate concrete was 15%, where if exceeded, it will decrease the compressive strength. The experimental results obtained and observation made in this study indicated that fly ash possesses the potential used as a strength development agent as a partial replacement for cement in producing concrete.
