Production method of novel building material

Abstract

The invention belongs to a production method of a novel building material. The production method comprises the following steps of 1, mechanically crushing building waste obtained after a building is detached and dug into reclaimed sand in the fine sand state; 2, utilizing the reclaimed sand for preparing concrete and mortar. By means of the production method of the novel building material, the problems that environment pollution is caused by waste discharged when the building is detached and dug, and natural sand sources are lacked are effectively solved, and the problems of stacking occupation, and environment pollution of the urban waste are reduced. It is proved through experiments that compression strength, mechanical performance, freezing resistance, carbonizing performance and the like of masonry mortar and concrete prepared by the reclaimed sand all reach or exceed the design standards, and the production method has significant economic benefits and social benefits.

Description

technical field [0001] The invention relates to a green recycled building material produced by using the waste discharged from demolished buildings, in particular to a production method of a new type of building material. Background technique [0002] With the development of the economy, people's requirements for the quality of life are getting higher and higher, and there are new demands for building materials. Not only high-quality, long-life building materials are required, but also higher requirements for building performance. Require. [0003] At present, the waste concrete discharged from the demolition of buildings is the largest waste in the construction industry. The discharge of waste concrete is increasing every year, causing serious environmental problems and causing secondary pollution to the environment. However, sand and gravel aggregates, which are the most used in the production of concrete in the construction industry, have been exhausted and in short supp...

Problems solved by technology

[0003] At present, the waste concrete discharged from the demolition of buildings is the largest waste in the construction industry. The discharge of waste concrete is increasing every year, causing serious environmental problems and causing secondary pollution to the environment.

However, sand and gravel aggregates, which are the most used in the production of concrete in the construction industry, have been exhausted and in short supply in a few areas. and natural landscape
