Abstract

The invention discloses a steel fiber / fly ash / red mud water-permeable brick and a preparation method thereof. The steel fiber / fly ash / red mud water-permeable brick is prepared from the following raw materials in parts by weight: 50-70 parts of steel fiber, 15-20 parts of red mud, 20-30 parts of fly ash and 30-40 brick slag particle. The invention also discloses a preparation method of the water-permeable brick. The steel fiber, brick slag particle, fly ash and red mud used as the raw materials are mixed to prepare the water-permeable brick. The brick slag and fly ash are recovered wastes, the red mud is the recovered low-cost raw material, and the cost of the steel fiber is not high; and thus, the low-cost raw materials are utilized to recycle the wastes. The raw materials are sintered at sintering temperature to obtain the high-strength high-water-permeability high-wear-resistance water-permeable brick.

Description

technical field [0001] The invention belongs to infrastructure construction materials, and in particular relates to a permeable brick capable of solving urban ground surface hardening and simultaneously having high strength and high wear resistance, and also relates to a preparation method of the permeable brick. Background technique [0002] Ordinary floor tiles laid on the surface of the city will harden the surface after draining the rainwater due to long-term lack of moisture, and more serious excessive length will cause continuous ground subsidence. Therefore, it is necessary to use permeable bricks to solve this difficult problem. [0003] Commonly used ordinary permeable bricks: porous concrete materials made of ordinary crushed stones are pressed and formed, and are used for sidewalks and squares in general blocks. They are general paving products. It has low strength and poor wear resistance, resulting in a low service life. [0004] There is also a kind of polyme...
