Quartz sand water permeable brick

Abstract

The invention relates to a quartz sand water permeable brick, which is prepared from the following components in parts by weight: 230 to 337 parts of quartz sand, 32 to 54 parts of slag, 73 to 94 parts of cement, 12 to 15 parts of thermal insulating bead, 32 to 36 parts of water, 6 to 14 parts of mortar coagulator, 5 to 9 parts of dyeing agent, 11 to 13 parts of cementing agent, 2 to 6 parts of coloring agent, 340 to 531 parts of fine stone aggregate, 1 to 4 parts of pigment, 9 to 13 parts of cement enhancer and 12 to 14 parts of accelerator. The quartz sand water permeable brick has the advantages that a formula is scientific, and the material selection is convenient and easy. Waste expanded quartz sand with different specifications is taken as a main material, the weight of a product is lighter than that of a product prepared by adopting sandy gravel; the waste slag is used for extracting the thermal insulating bead which is then added in the product, so that the water permeation effect is higher. The quartz sand water permeable brick has excellent wear resistance; the product is bright and varicolored in color, is unfading, and is moldable in shape, and fully embodies diversity and individuation.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a quartz sand 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...
