Embodiment Construction

[0009] The present invention is a high-performance permeable brick. According to the percentage by weight, the composition of the permeable brick is: 68% of limestone aggregate with a diameter of 6-9 mm, 21% of 32.5 cement, 10.4% of water and 0.6% of water reducer.

[0010] The preparation process steps of the high-performance permeable brick are as follows: put in limestone aggregate according to the ratio, pre-add 40% of the total water and mix evenly, then add cement and mix evenly, add the remaining 60% of the total water and mix evenly, and finally add reducing The water solution is stirred for 20 seconds, and is formed by high-frequency vibration and pressure.

Abstract

The invention mainly relates to the field of building materials, in particular to a high-performance pervious brick used on municipal roads, in residential blocks, on sidewalks of garden squares and in public places and a preparation process thereof. The high-performance pervious brick comprises, by weight percent, 68% of limestone aggregate, 21% of cement, 10.4% of water and 0.6% of water reducer. The pervious brick produced through the process maintains higher water percolation rate, and lives up to the standard in strength and frost resistance.

Description

technical field [0001] The invention mainly relates to the field of building materials, in particular to permeable bricks used for municipal roads, residential quarters, sidewalks in garden squares and public places and a preparation process thereof. Background technique [0002] Permeable bricks have the following advantages: 1. Create a comfortable living environment with the function of water permeability and water storage; 2. Alleviate the urban heat island effect; 3. Help the growth of trees on both sides of the road; 4. Slow down the pressure on the urban drainage system; 5. Effective Replenish groundwater; 6. Anti-slip and wear-resistant. [0003] In Guizhou, in the actual production of traditional permeable bricks, since most of the local raw materials are limestone, and the limestone aggregate has a high water absorption rate, the permeable bricks produced with it cannot meet the water permeability required by the national industry standard JC / T945-2005.
