Abstract

The invention discloses a high-strength water-permeable brick for an urban channel revetment. The high-strength water-permeable brick for the urban channel revetment comprises the following raw materials in parts by weight: 110 to 120 parts of aggregate, 35 to 45 parts of silicate cement, 20 to 40 parts of diatomite, 15 to 30 parts of water, 12 to 18 parts of forming stabilizer, 20 to 40 parts ofriver sand, 1 to 2 parts of water-reducing agent and 1 to 2 parts of dispersing agent. The high-strength water-permeable brick for the urban channel revetment has high compressive strength, is not liable to deformation, can effectively reduce urban garbage and save the use amount of natural aggregate, is low in cost, high in strength, dense in surface, energy-saving and environment-friendly, has high water-permeable and air-permeable properties, enables rainwater to be permeated into underground rapidly and improves the life quality of people in the city.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a high-strength permeable brick for urban river revetment. Background technique [0002] The impermeable river revetment is very harmful to the urban environment. In the event of heavy rain in many cities, the accumulated rainwater cannot seep quickly, which can easily cause urban waterlogging and deteriorate the revetment greening environment, resulting in a decline in urban ecological benefits and affecting people's quality of life in the city. How to prepare a kind of permeable brick for river revetment, which has high strength on the basis of ensuring the water permeable effect, and can meet the pavement requirements of urban river revetment, has become a technical problem to be solved at present. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a high-strength permeable brick ...
