Abstract

The invention discloses a water permeable brick prepared from construction waste and a preparation method of the water permeable brick, and belongs to the technical field of building materials. According to the water permeable brick, the construction waste serves as an aggregate, and kaolin, fly ash, water reducing agents and water are added, wherein the construction waste aggregate mainly comprises waste concrete, waste tiles, waste stone, ceramsite, waste gypsum and waste glass. The water permeable brick has the advantages that the problem of resource waste is solved, and resources are recycled; the air permeable brick with high water permeability, high strength and good sound absorption effect is obtained through reasonable material selection and raw material grading, and has a good reduction effect on noise pollution caused by urban pavement construction, especially noise pollution caused by vehicles on the road to surrounding houses; due to the good absorbing effect on low frequency noise, the water permeable brick can be also applied to pavement laying for tunnel lights to reduce tunnel noise pollution. The preparation process of the water permeable brick is simple, and production and manufacture are facilitated.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a permeable brick prepared from construction waste. Background technique [0002] Permeable brick is an urban permeable pavement material that has developed rapidly in recent years, and is favored by municipal departments of various cities. With the rise and development of sponge city construction, the demand for permeable bricks is increasing. However, the existing permeable bricks can only meet the general water permeability requirements, the water permeability is not high, the flexural strength is low and the function is relatively single. In addition, with the rapid development of urban construction and the sharp increase of urban traffic, the construction of traffic roads and residential houses has been accelerated. Due to the widening of roads and people's large demand for residential houses, many houses are built close to the roads, causing serious noise pollu...
