High-performance pervious brick and preparation process thereof

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. Strength a...
