Abstract

The invention provides a tailings-ceramsite light permeable brick and a preparation method thereof. The method includes preparation of tailings ceramsite and the tailings-ceramsite light permeable brick. The tailings-ceramsite light permeable brick is prepared from, by weight, 1000 parts of the tailings ceramsite, 250-300 parts of cement, 30-50 parts of suspended roasting iron tailings, 0-30 partsof silicon ash, 0-80 parts of coal ash, 2.8-3.0 parts of a water reducer and 100-120 parts of water; the tailings ceramsite comprises, by weight, 20%-30% of the suspended roasting iron tailings, 40%-60% of molybdenum tailings, 15%-25% of the coal ash and 5% of coal dust. The tailings-ceramsite light permeable brick has the advantages of excellent performance, light weight, high strength, high permeable coefficient, low cost and good social and economic benefits.

Description

technical field [0001] The invention relates to the field of building materials, in particular to tailings ceramsite lightweight permeable bricks and a preparation method thereof. Background technique [0002] In the process of urbanization, the surface of modern cities is gradually hardened and covered by water-blocking materials such as buildings and bricks. This "hardening" of the surface makes it difficult for atmospheric precipitation to penetrate into the ground in time, and the surface runoff increases, forming the "heat island effect". As well as environmental problems such as waterlogging and urban surface subsidence caused by insufficient drainage. [0003] The traditional pavement structure uses impermeable pavement materials, that is, the surface layer and the base layer are paved with dense materials, and it is difficult for surface water to penetrate into the roadbed. With the strengthening of people's awareness of environmental protection, various disadvantag...
