Water permeable brick

Abstract

The invention relates to water permeable brick. The water permeable brick is prepared from the following components in parts by weight: 230 to 337 parts of quartz sand, 100 parts of iron tailings super-fine sand, 73 to 94 parts of silicate cement, 4 to 6 parts of epoxy resin GCCI35, 32 to 36 parts of water, 1.20 to 1.92 parts of curing agent GCCI37, 6 to 14 parts of mortar coagulating agent, 0.08 to 0.18 part of silane coupling agent KH550, 55 to 70 parts of air entraining agent, 11 to 13 parts of cementing agent, 1.5 to 2.1 parts of admixture, 340 to 531 parts of fine store aggregates, 1 to 4 parts of pigments, 9 to 13 parts of cement reinforcing agent and 12 to 14 parts of accelerating agent. The water permeable brick has the advantages that by using waste residue iron tailings as aggregates, the aggregates are different from common water-permeability concrete, and therefore, the aggregates are novel building materials; the water permeable brick is manufactured by developing and utilizing the iron tailings, so that the cost of the concrete can be greatly reduced, the problems of construction cost, and compressive strength, water permeability and surface blocking of the water permeable brick can be solved, and sustainable development is achieved.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a permeable brick. Background technique [0002] With the development of urbanization, more and more hard ground is laid in the city, which has poor environmental protection function and is not suitable for human habitation. For example, the heat island effect of the concrete floor, ground water and urban waterlogging caused by poor drainage, and the inability of natural precipitation to infiltrate and replenish groundwater lead to the destruction of the groundwater cycle. Existing concrete pavement bricks are a typical hard ground, mostly solid bricks, with a very low water permeability coefficient and basically no water permeability function. [0003] Due to the demand of "sponge city", various permeable materials have been widely used in municipal greening projects. As a widely used material with mature technology, simple construction and low cost, permeable brick is the main ma...
