The generated electric porcelain waste increases with the rapid development of the electric porcelain industry. Unreasonableutilization results in the waste of resources and environmental pollution. However, at present, many coal gangues and fly ashesare wasted and underutilized in my country. In this paper, electric porcelain waste is used as the main raw material, and itssintering temperature, holding time, and heating rate are discussed to study the performance of the permeable brick preparedfrom electric porcelain waste. Results show that with the increase in sintering temperature, the porosity and waterpermeability coefficient of permeable bricks decrease, and their volume shrinkage rate and compressive strength show anincreasing trend. Furthermore, porosity decreases with the increase in holding time. The volume shrinkage rate andcompressive strength increase, and the water permeability coefficient decreases. The volume shrinkage rate of the permeablebrick decreases, and its porosity, water permeability coefficient, and compressive strength increase with the heating rate. Combined with the comprehensive consideration of the porosity, volume shrinkage rate, water permeability coefficient, andcompressive strength of permeable bricks, the best sintering process for preparing permeable bricks from electrical porcelainwaste is presented with a sintering temperature of 1225 °C, holding time of 1 h, and heating rate of 6 °C/min. The porosityof the prepared permeable brick is 79.5%, the volume shrinkage rate is 25.79%, the water permeability coefficient is 2.82×10-2cm/s, and the compressive strength is 5.79 MPa.
