Abstract

The production process of bricks made from waste mud was optimized in this study by investigating the effects of various factors on compressive strength, including curing agent formula, molding pressure, moisture content, and dosage. Economic benefits were also analyzed based on market conditions, demonstrating the high potential of the bricks. The waste mud was identified as fine sand soil consisting mainly of quartz and clay minerals. Portland cement was identified as the optimal curing agent, and higher molding pressure was found to increase compressive strength. Lower moisture content resulted in a shorter time to form mechanical strength. The study also showed that low maintenance temperatures had little effect on early compressive strength. Overall, this process successfully reduces and utilizes waste mud from slurry shield tunnels.
