Paving blocks and cement concrete tiles are two of the most used precast solid cement concrete products. Cement is the primary component required to create the product, and both are widely available across the Philippines, but its cost is increasing day by day. Currently, several waste products such as cow bones, which undergo processes to be pulverized, are used to replace one or more constituent materials in the production of concrete and paving blocks.
This study seeks to evaluate the effect of the possible use of Pulverized Cow Bone (PCB) as a partial replacement for cement in paving blocks. The compressive strength, density, workability, and water absorption tests are made with Ordinary Portland Cement (OPC) that was partially replaced with pulverized cow bone in percentages of 10%, 15%, and 20%. The samples were made in a 200 mm x 100 mm x 60 mm mold and then subjected to a 14 and 28- day curing period by watering them as frequently as possible before testing. The samples of concrete paving blocks were tested through the Digital Display Compression Testing Machine for their perspective compressive strength.
Based on the results, the relationship of water absorption and density to compressive strength shows that as the water absorption and density increases the compressive strength also increases. This implies that the compressive strength of the paving blocks is directly proportional to both water absorption and density. Furthermore, the partial replacement of Ordinary Portland Cement with Pulverized Cow Bone shows a gradual decrease in the compressive strength, water absorption and density. This indicates that the percentage of pulverized cow bones is inversely proportional to the compressive strength, water absorption and density. The use of pulverized cow bone waste as partial replacement in cement material has vital importance to produce low-cost concrete and helps to conserve materials needed for cement production. Hence, the findings revealed partially replacing the cement with pulverized cow bones is ineffective in terms of its mechanical properties.
