Process for producing light wallboard block by using construction waste

Abstract

The invention relates to a process for producing a light wallboard block by using construction waste. The process flow comprises the following steps: (1) crushing the construction waste, and screening to obtain construction waste micro powder with the particle size of less than 0.15 mm; 2) putting the construction waste micro powder and cement into a stirrer for dry stirring; (3) stirring the quicklime powder, the anti-crack waterproof agent, the aluminum powder and the water into slurry; the light wallboard block produced through the method is stable and uniform in quality, meanwhile, the production process is simple, operation is convenient and fast, and high economical efficiency is achieved.

Description

technical field [0001] The invention relates to a process for producing lightweight wall panels from construction waste, and belongs to the field of solid waste utilization and building energy-saving wall materials. Background technique [0002] With the continuous deepening of the reform of wall materials in our country, clay, as a non-renewable resource, has been paid more and more attention by people. In order to protect clay resources, the production and use of wall materials using clay as raw materials has been gradually banned in 160 large and medium-sized cities across the country. Therefore, a large number of new wall materials have emerged in recent years, and autoclaved lightweight concrete wall panels are one of them. [0003] Autoclaved lightweight concrete wall panels are lightweight, porous, sound-insulating and heat-resistant environmentally friendly building materials. Autoclaved lightweight concrete wall panels mainly use some siliceous materials, calcareo...
