Water permeable brick with harmonious strength and water permeation performance and preparation method thereof

Abstract

The invention discloses a water permeable brick with harmonious strength and water permeation performance. The water permeable brick is prepared from, by weight, 34-36 parts of Portland cement, 18-22parts of modified volcanic powder, 12-16 parts of porous powdery quartz-doped albite, 14-18 parts of silicon dioxide aerogel, 8-14 parts of active silicon dioxide powder, 2-5 parts of polyvinyl chloride, 2-4 parts of reinforced fibers, 4-8 parts of sodium citrate, 1-3 parts of rubber powder and 12-18 parts of deionized water. The water permeable brick with harmonious strength and water permeationperformance, compared with the prior art, has the advantages that the water permeation performance and strength can be harmonized, and the water permeable brick is suitable for large-scale productionand has a high use value and a great application prospect.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a permeable brick with coordinated strength and permeable properties and a preparation method thereof. Background technique [0002] Permeable bricks originated in the Netherlands. During the process of building the city from the sea, the Dutch found that the ground after the seawater was drained would cause continuous land subsidence due to long-term lack of water. Once the dykes on the coastline were washed away, the seawater would quickly Rush to a city much lower than the sea level and submerge the entire coastal city. In order to prevent the ground from sinking, the Dutch made a small pavement brick with a length of 200 mm, a width of 100 mm, and a height of 50 or 60 mm. , and reserved a gap of 2 mm between the bricks, so that when it rains, the rainwater will seep into the ground from the gap between the bricks. This is the famous Dutch brick, ordinary permeable br...

Problems solved by technology

[0003] Although the existing permeable bricks have good water permeability, their strength is poor and easy to damage, and the two cannot be coordinated. Chinese patent literature (publication number: CN106518032B) discloses a permeable brick and its preparation method. Through the permeable surface layer, its aggregate is Sand with a particle size of 0.4-0.9mm; permeable base, whose aggregate is controlled by sand with a particle size of 0.4-1mm, so that proper pores can be formed between the permeable surface layer of the permeable brick and the permeable base layer, and the porosity can be ensured Reasonable, although the permeable brick has good water permeability, its strength is not very good and it is easy to damage

[0004] Chinese patent literature (publication number: CN108046705A) discloses a preparation method of high-strength zeolite permeable bricks. First, the resin is carbonized and pulverized, and then modified by hydroxylation, and then alkali and aluminum source sodium metaaluminate are added with orthosilicate And in the mixed solution of modified carbonized skeleton particles, synthesize carbonized skeleton particles, under the action of potassium thiocyanate, improve the adsorption activity of molecular sieves, and deposit carbonized skeleton particles of high adsorption activity zeolite molecular sieves on the surface and lemon juice, tartaric acid and zeolite Acid bacteria blend fermentation to improve the hydrophilicity of zeolite, to obtain self-made permeable filler, and finally, compound the self-made permeable filler with cement, sodium silicate solution, etc. Cement, sodium silicate solution and other compound injection membrane, although the strength of the permeable brick is good, but the water permeability is poor
