Abstract

The invention discloses an environment-friendly exterior wall hanging plate doping with construction waste and a preparation method thereof. The environment-friendly exterior wall hanging plate is prepared by mixing the following components in parts by weight: 25-175 parts of construction waste, 75-100 parts of cement, 0-150 parts of sand, 0-1 part of water reducing agent, 0-1 part of thickening agent, 2-18 parts of cold drawn wire and 19.5-30 parts of water. Proved by experiments, the construction waste added in the exterior wall hanging plate improves the performance indexes of anti-breaking force, and the like of the exterior wall hanging plate, a large quantity of the construction waste can be consumed, and the use level of partial cement and sand is reduced, thereby utilizing the waste, saving the resources and protecting the environment. The invention has great function in the field of construction and has wide market prospect.

Description

technical field [0001] The invention relates to the field of building materials, and mainly relates to the reuse of industrial waste materials, in particular to an environment-friendly exterior wall hanging board mixed with construction waste and a preparation method thereof. Background technique [0002] As one of the pillar industries of the national economy, the construction industry has developed by leaps and bounds in recent years, but the resulting construction waste is also increasing. According to statistics, in 2005, the total amount of waste concrete in my country (the sum of waste concrete in the concrete production process, building construction process and building demolition process) will reach more than 120 million tons. With the further acceleration of my country's economic construction, the total amount of waste concrete will increase. Such a huge amount of waste concrete will cause great environmental problems, economic problems and even social problems. ...
