Abstract

The invention relates to a waste brick recycled concrete building material and a manufacturing method thereof. The manufacturing method comprises the following steps of: as waste brick blocks or crushed brick materials obtained from engineering construction and dismounted buildings are taken as a raw material, crushing, screening, classifying, removing dust and soaking to obtain brick aggregates, and stirring the brick aggregates, sand, cement and water according to a certain proportion to obtain a suitable fully-new building material. The waste brick recycled concrete building material can be used for producing high-strength brick blocks and can be also taken as a foundation filter, a roadbed material or a landscape road bridge material so as to relieve a problem that the building material is short. The waste brick recycled concrete building material produced by the producing method disclosed by the invention has the advantages of high strength, no pollution, low cost, wide application range, good sustainability and benefits and the like, matches national requirements on energy saving, environment friendly development, low carbon and economy. Therefore, the material and the method can contribute economic construction and can also reduce consumption of natural resources.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a new green and environment-friendly building material regenerated from waste bricks and broken bricks in engineering construction or dismantled buildings and a production method of the recycled building materials. Background technique [0002] Brick is a traditional wall material in my country and is widely used. There are about 120,000 brick enterprises in the country, covering an area of ​​more than 5 million mu, and burning bricks destroys 120,000 mu of land every year. Although the use of solid clay bricks is prohibited in policy, however, various types of bricks are still widely used due to the advantages of local materials, cheap price, durability, fire prevention, heat insulation, sound insulation, and moisture absorption. . With the rapid development of urban construction, demolition and construction changes of new and old towns, coupled with the impact of some...
