Abstract

The invention discloses a high-strength and high-water permeability ceramic water permeable brick and a preparation method thereof. The high-strength and high-water permeability ceramic water permeable brick comprises the following raw materials in part by weight: 60-80 parts of porous coarse aggregates, 30-40 parts of ceramsite, 20-30 parts of cement, 10-30 parts of calcined metakaolin powder, 10-20 parts of fly ash, 5-15 parts of coal gangue, 3-8 parts of coal ball micro-powder, 2-8 parts of fibers, 1-5 parts of a pore-forming agent, 0.3-0.8 part of a water reducer and 0.1-0.5 part of sintering aid. The water permeable brick disclosed by the invention is excellent in water permeability, high in strength, good in wear resistance, and convenient and quick to construct, also has the functions of water storage, dehumidification and humidification and is used on a pavement to relieve the pressure caused by too much rain to the urban pavement and reduce the urban surface temperature.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength and high-permeability ceramic permeable brick and a preparation method thereof. Background technique [0002] Water resources have become a decisive factor for the sustainable development of a country. The high density of population and dense building complexes in modern cities have caused urban hardening, which is ecologically known as "artificial deserts". With the intensification of urbanization development, whether it is sidewalks, streets, squares, or courtyards in residential quarters, pavements are mostly paved with closed structures such as granite, cement, and glazed bricks, but the urban water permeability is weakening. The urban surface is gradually being covered with water-blocking materials such as buildings and various concretes, and the proportion of impervious areas is increasing significantly. That is to say, the surface coverage of th...
