Abstract

The invention belongs to the field of resource utilization of inorganic solid waste and specifically relates to a self-cleaning ecological permeable brick and a preparation method thereof. The ecological brick comprises the following ingredients (by weight): 65-85 parts of aggregate particles, 1-5 parts of carbonate, 4-10 parts of phosphate, 1-3 parts of alkali metal oxide, 1-3 parts of a photocatalyst preparation and 5-15 parts of water. The permeable brick has a self-cleaning function. The problem of pore blocking due to microbial growth and adhesion during the long-term use process of a permeable brick product can be effectively improved. Meanwhile, the permeable brick also has advantages of high strength, good endurance, excellent water permeability and the like. Specifically, compressive strength is greater than or equal to 35 MPa; permeation coefficient (15 DEG C) is greater than or equal to 1.5*10<-2> cm / s; water-retention rate is greater than or equal to 0.10 g / cm<-3>; and wear crater length is less than or equal to 25 mm.

Description

technical field [0001] The invention belongs to the field of resource utilization of inorganic solid waste, and in particular relates to a self-cleaning ecological permeable brick and a preparation method thereof. Background technique [0002] With the rapid development of my country's urbanization process, the modern urban stormwater management system has gradually attracted people's attention. Sponge city construction is a new generation of urban stormwater management concept proposed to adapt to urban environmental changes and deal with rainwater disasters. Permeable brick products are a core component of sponge city construction. The water permeability of road and square pavement plays an important role in the penetration, retention and purification of urban rainwater. The research and application of pavement materials such as permeable bricks are increasing. [0003] Common types of permeable bricks in the Chinese market mainly include resin sand-based permeable brick...
