Burned brick production from residues of quarrying process in Thailand

In Thailand, the residues of the quarrying process are classified as industrial waste. The residues can block the drainage system, causing the country's flooding problem. This research focused on producing burned bricks for construction with the utilization of the residues. In this experiment, the residues and clay were mixed at different ratios:0%, 40%, 50%, 60%, 70%, and 80% by weight, and then burned at different temperature levels: 900 degrees C, 1000 degrees C, and 1100 degrees C.The results showed that the condition of 50%-60% content of the residues, burned at 1000-1100 degrees C gave the high compressive strength of 42.50-43.67 MPa.The 40%-60% residues mixed with clay could increase the compressive strength, which was 1.5 times greater than the case of clay (or 0% residue). In addition, at burning 1000-1100 degrees C had caused the sintering process to result in high compressive strength.
