The rising demand for construction materials has led to significant consumption of natural resources, particularly sand and cement, which are essential for making cement bricks. To address this issue, research has been conducted on incorporating waste materials from agricultural and industrial sources, such as cocopeat (CP) and silico-manganese (SiMn) slag as partial replacements in cement bricks. In this study, several samples of cement bricks were prepared using a sand-to-cement ratio of 1:2.5, a water-to-cement ratio of 0.5, and replacement materials consisting of 5–15% CP and 10–20% SiMn. The results revealed that higher CP content decreases compressive strength and density due to its porous structure, whereas SiMn increases strength by enhancing particle packing and acting as a binding agent. With that, the optimal mix was identified at 5% CP and 15–20% SiMn, which achieved improved strength while maintaining water absorption within industrial standard requirements, thereby ensuring structural durability. Additionally, the partial replacement of sand and cement with cocopeat and silico-manganese slag reduced the density of the bricks, making them easier to handle and decreasing structural loads. The use of CP and SiMn not only supports sustainable waste management but also improves the mechanical properties of the bricks.
