Abstract

The disclosure provides a ferro-aluminate lightweight thermal insulation wall material based on industrial solid waste and a preparation method. The raw material of the wall material is composed of solid raw materials and water, and the solid raw material is composed of ferro-aluminate cement based on industrial solid waste and recycled materials. , foaming agent, aggregate, air-entraining agent, and reinforcing materials. The raw materials of ferro-aluminate cement based on industrial solid waste are composed of red mud, steel slag, slag, desulfurized gypsum, silica fume, and aluminum ash. The preparation method is as follows: red mud, steel slag, slag, desulfurized gypsum, silica fume, and aluminum ash are sequentially ground through raw materials, homogenized, fired, and clinker ground to obtain iron-aluminate cement based on industrial solid waste. The iron-aluminate cement of industrial solid waste is stirred with recycled materials, water, foaming agent, aggregate, air-entraining agent, and reinforcing material to form foam. The disclosure can prepare light-weight thermal insulation wall materials from industrial solid waste, greatly improves the utilization rate of solid waste, has high fluidity and light weight characteristics, and at the same time, has higher strength and better thermal insulation effect and other properties.

Description

technical field [0001] The disclosure belongs to the field of building materials, and relates to a ferroaluminate light-weight thermal insulation wall material based on industrial solid waste and a preparation method. Background technique [0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] With the rapid development of my country's economy, a large amount of energy consumption has produced a large amount of industrial solid waste, which mainly includes red mud, steel slag, desulfurized gypsum, smelting slag, tailing sand and coal gangue. At present, my country's industrial solid waste discharge exceeds 3 billion tons per year, and the effective disposal rate is only about 60%. With the contin...
