Ecological self-cleaning clog-proof water permeable brick based on construction waste and preparing method thereof

Abstract

The invention provides an ecological self-cleaning clog-proof water permeable brick based on construction waste and a preparing method thereof. The method comprises the following steps of adding water into city sludge, brick slag and concrete, stirring until the aggregate is fully damp, then adding cement, a water reducing agent and a polymer fiber, stirring, then adding a high-molecular polymer and water, stirring until the surface of the mixture is bright, and pressing to form a water permeable base layer; fully mixing nanometer titania and the high-molecular polymer with water, then adding water into slag, steel slag, the brick slag and concrete slag, stirring until the aggregate is fully damp, then adding the two mixtures into the cement and the water reducing agent, mixing, placing the mixtures on the surface of the water permeable base layer, conducting vibration and extrusion molding, and finally after a water permeable surface layer and water permeable base layer composite brick are fully dried, obtaining ecological self-clean clog-proof water permeable brick based on the construction waste by high temperature stoving.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an ecological self-cleaning anti-blocking permeable brick based on construction waste and a preparation method thereof. Background technique [0002] With the development of the city, ordinary concrete is used in every corner of the city, such as roads, buildings, squares, etc. The surface of ordinary concrete is hardened and airtight. Although it greatly facilitates people's travel, it also prevents ground water The circulation with groundwater affects the cycle development of water in nature, increases the burden of urban sewage discharge, affects the replenishment of groundwater, and easily causes urban heat island effect. Therefore, in order to improve people's living environment and improve people's Quality of life, ecological permeable bricks are one of the favorable ways to improve the urban ecological environment. [0003] At present, according to the differ...
