Abstract

The invention provides an autoclaved self-insulation block and a production method thereof and relates to the technical field of building materials. The autoclaved self-insulation block is made from building waste, carbide slag, flyash, lightweight ceramsite, a crystal modifier, stone flour, and mineral waste residue; the autoclaved self-insulation block produced herein has good properties, has small density, high density and small thermal conductivity coefficient and has good self-insulation effect; the materials for the autoclaved self-insulation block are widely sourced, the solid wastes such as building waste are recyclable, land utilization and environmental pollution due to solid waste accumulation are decreased, the environment is protected, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an autoclaved self-insulating block and a preparation method thereof. Background technique [0002] With the development of social economy, the country attaches great importance to energy conservation and improvement of living conditions. Building energy conservation is an important field of energy conservation work in my country; the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Commerce, and the State Intellectual Property Office, in 2007 In the "Guidelines for Key Fields of High-tech Industrialization with Priority Development" promulgated and implemented on January 23, 2010, it was clearly stated that "priority should be given to the development of high-performance exterior wall self-insulating wall materials". At present, there are many kinds of self-insulating wall materials commonly used in the construction fi...
