Abstract

The invention discloses a multifunctional water permeable brick and a preparation method thereof. The multifunctional water permeable brick is formed by a base layer and a covering layer covering thebase layer, wherein a thickness ratio of the base layer to the covering layer is (1 to 3):1; the covering layer is prepared from the following raw materials in parts by weight: 40 to 45 parts of sludge, 20 to 23 parts of common stones, 15 to 18 parts of steel slag, 8 to 10 parts of pulverized fuel ash, 10 to 15 parts of ceramsite, 12 to 15 parts of sodium silicate, 10 to 12 parts of quartz sand, 10 to 15 parts of a wave-absorbing material, 6 to 7 parts of palm fiber and 2 to 3 parts of sepiolite fiber. The multifunctional water permeable brick having the base layer and the covering layer are prepared; through the matching of the base layer and the covering layer, the capacity of absorbing electromagnetic waves is given to the multifunctional water permeable bricks through the covering layer, blockage-proof capacity is also integrated, and good water permeability is maintained by the multifunctional water permeable bricks through the base layer.

Description

technical field [0001] The invention relates to the technical field of sponge city building materials, and more specifically, to a multifunctional permeable brick and a preparation method thereof. Background technique [0002] In recent years, the problem of urban waterlogging has attracted much attention. In the traditional urban construction model concept, rainwater is mainly drained through drainage facilities. Water accumulated on the road cannot penetrate into the ground, and rainwater resources are not fully utilized. Negative environmental impacts such as the heat island effect. At present, my country's solutions to the above problems mainly include increasing the diameter of drainage pipes, online water storage, and building reservoirs, etc., but these measures not only generally have many disadvantages such as large investment and large space occupation, but also long construction time and low efficiency. . The construction of sponge city can better solve the probl...
