Abstract：The blast furnace slag-based permeable brick was prepared by taking cement and slag as main binding material,granulated blast furnace waste slag in metallurgical industry as aggregate.The paper analyses the main influence factor to properties of permeable brick,and used orthogonal method to find reasonable formulation and process parameters.The results showed that 390 kg/m3 cementitious material,0.38 W/B,770 kg/m3 setting weight and 15 s vibration time are optimum technological parameters.Its splitting tensile strength is 3.8 MPa,and the pervious coefficient is 14.1×10-2 cm/s,which satisfied the requirement stipulated in standard GB/T 25993-2010 "Permeable paving bricks and permeable paving flags",and has been well applied to the sponge city project in Wuhan.
