Ceramic permeable pavement brick and preparation method thereof

Abstract

The invention discloses a ceramic permeable pavement brick. The ceramic permeable pavement brick comprises the following components in parts by weight: 50-60 parts of barite, 15- 25 parts of microlite, 2-5 parts of titanium dioxide, 5-10 parts of quartz sand, 5-8 parts of zirconium dioxide, 20-30 parts of enhanced clay, 5-10 parts of an activator, and 0.5-2 parts of auxiliary additives. The ceramic water pavement brick has the advantages of good water permeability, high material strength, good abrasion resistance, weathering resistance and long service life, and the preparation method has the advantages of low cost, easy availability of raw materials, and simple process, and has great practical value and good application prospect.

Description

technical field

[0001] The invention relates to the technical field of building ceramic materials, in particular to a ceramic pavement brick and a preparation method thereof. Background technique

[0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, water supply, drainage and other water recycling links should be coordinated, and its complexity and long-term nature should be considered. As we all know, most of the existing urban street pavements are paved with impermeable materials such as cement concrete, asphalt, and stone. This hardened pavement is no longer suitable for the trend of building sponge city pavements.
