Abstract

The invention relates to the technical field of building materials and in particular relates to a novel pressure-resistant anti-cracking water permeable brick which comprises the following raw materials: basalt aggregate, quartz sand, cement, coal ash, an inorganic pigment, octadecyl trimethyl ammonium chloride, a foaming agent, a hydrophobic modification ore fiber, a water reduction agent and water, wherein the hydrophobic modification ore fiber is an inorganic fiber with surface hydrophobic modification treatment; the inorganic fiber is a mixture of a brucite fiber and a wollastonite fiber;the basalt aggregate is crude aggregate which is crushed by using a jaw crusher and has a particle size of 1.5-3mm after screening; the foaming agent is hydrogen peroxide. The novel pressure-resistantanti-cracking water permeable brick has good water permeability and wearing resistance, and in addition, the brick is high in strength, very excellent in pressure resistance and not liable to crack when being used.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel pressure-resistant and crack-resistant permeable brick. Background technique [0002] With the continuous development of urbanization, more and more land is used to build high-rise buildings and roads. Hardened roads and building land are usually impervious to water, so poor drainage often occurs in cities during heavy rains in summer and road water problems. In recent years, in order to solve the problem of urban waterlogging in summer, more and more cities have proposed the concept of sponge city construction. This construction concept improves the ability of urban infrastructure to absorb rainwater and drain underground through large-scale urban green spaces, extensive underground drainage corridors and the use of permeable building materials. Among them, the permeable brick is this kind of road paving building material with good water seepage performance....
