Embodiment 1
[0070] In order to achieve the above object, the technical scheme adopted in the present invention is:
[0071] 1. A method for preparing a ceramsite permeable brick with an interception effect on pollutants, comprising the following steps:
[0072] (1) Preparation of surface layer ceramsite: it is composed of 50% sludge (water content 40%), 20% coal gangue, and 30% construction concrete waste. Crush and grind the construction waste (construction concrete waste) and coal gangue (300 mesh), dry the sludge, mix and stir, stir for 10 minutes at a speed of 30-100rpm, and then pressurize (500kg / cm 2 ) forming, sintering at 1100-1200°C for 30 minutes, cooling to room temperature, and sieving to obtain 1mm surface layer ceramsite.
[0073] (2) Preparation of base ceramsite: it is composed of 40% sludge with a water content of 50%, 20% coal gangue, and 30% construction concrete waste. Crush and pulverize the construction waste (construction concrete waste), press dry the sludge, the...
Embodiment 2
[0089]1. The preparation method of the ceramsite permeable brick with interception effect on pollutants is similar to Example 1, and the difference is that it comprises the following steps:
[0090] (1) Preparation of surface layer ceramsite: it is composed of 40% sludge (water content 50%), 30% coal gangue, and 30% construction waste bricks. The construction waste bricks and coal gangue were crushed and powdered (300 mesh), the sludge was pressed dry, mixed and stirred, then pressurized and formed, sintered at 1200°C for 30 minutes, cooled to room temperature, and sieved to obtain surface layer ceramsite with a particle size of 2mm.
[0091] (2) Preparation of base ceramsite: it is composed of 50% sludge (water content 40%), 20% coal gangue, and 30% construction concrete waste. The construction waste is crushed and ground, the sludge is pressed dry, and then mixed and stirred, then pressurized and formed, sintered at 1200°C for 30 minutes, cooled to room temperature, and siev...
Embodiment 3
[0106] The difference from Example 1 is that the reinforcing agent in this example is made by mixing the following raw materials by weight: 30 parts of aluminum sulfate, 20 parts of silicon dioxide, 18 parts of aluminum oxide, 7 parts of limestone powder, and 12 parts of fly ash 13 parts, 13 parts of naphthalene sulfonate, 15 parts of cement anti-seepage and waterproofing agent.
