ABSTRACT
The development of the porous inorganic material materials began in the 1930s. SaintGobain company was first developed with calcium carbonate as the foaming agent of porous glass in 1935 (Zhang et al. 2010). At present, China and the United States are the main production agent countries of porous ceramics (Tian et al. 2014). With the improvement of people environmental protection consciousness, people began to attach importance to the sustainable development cycle use of solid wastes. Porous ceramics is prepared by using ceramics as the main raw material, by adding foaming agent and a porous material of various kinds of modified additives (Gao et al. 2014). Its interior is
were placed in two ball milling tanks; water was added to the mixture and grinding balls were prepared such that the ratio of the weight of materials to the ball to the water is 1:2:1. After that, the mixture was milled in a ball mill for 2 hours and the mixture was placed in an oven to dry and ground to powder. Oily soil and waste glass raw materials were made to pass through a 100 mesh screen. According to Table 2, oily soil, waste glass, and calcium carbonate were mixed in different proportions and the mixture was pressed into a substrate at a pressure of 10 MPa. It was placed in a muffle furnace for sintering in an air atmosphere. The sintering system is given as follows: first the speed was increased at the rate of 7°C/min up to reaching 400°C, and then was held for 30 min. The furnace temperature was then increased at the rate of 15°C/min up to reaching the foaming temperature of 850°C, and then was held for 20 min. Finally, the speed was reduced at the rate of 15°C/min down to 600°C, and then was held for 30 min. Samples were removed from the furnace and allowed to cool.
