Abstract
This study investigated a partial replacement of clay by additives for bricks. The purified clay mixed with different volume percentage of additives (Asphalt and Straw from agricultural waste) as separate and both to cast as bricks with the standard dimensions of 18.5 × 8.5 × 6.5 cm3. Cylindrical pellets casted with the dimensions of average diameter of 40 mm and thicknesses about 2.5 ± 0.2mm. The casted bricks and pellets are air dried in open atmosphere for 8-10 days. These bricks and pellets are fired for three days, at the end of three days kiln is allowed to cool to reach room temperature. The sample bricks are tested for compressive strength and water absorption; pellets are tested for thermal conductivity and electrical conductivity. From the obtained results, it has concluded that the compressive strength slightly increased against density of the bricks. A moderate decrement observed in the water absorption against density of the samples and compressive strength weakens with the increment of water absorption of the samples. Improved electrical conductivities of the samples with additives appears change in electrical properties from insulating to semiconducting. Thermal conductivity values of the samples with additives are climb against the 100% clay sample. The result shows that the greatest thermal conductivity of 0.905 Wm-1K was obtained for 85% Clay / 5% Straw / 10% Asphalt sample. The additives enhance porosity and heat contact through the samples. The values obtained and with reference to the graphs plotted, can be concluded that the 90% Clay / 5% Straw / 5% Asphalt sample is superior among the samples.
