Problems solved by technology

[0002] At present, with the rapid development of the construction industry and the requirements of construction quality, lightweight building materials are gradually accepted by the market. The advantages of lightweight building materials are light weight, heat preservation, and also have effects such as sound insulation and fire prevention. Generally, cementitious materials, fillers, blending agents, and foaming agents are used. The cost of raw materials for original lightweight building materials is relatively high. Therefore, in recent years, various research institutions and construction manufacturers have been looking for alternative raw materials. At present, the mature filler is also the main material. Most of the used is fly ash, but with the rapid development of lightweight building materials, the source and use of fly ash are limited to a certain extent, so the production is limited to a certain extent, how to find other sources of fillers to produce high-quality High-quality and cheap lightweight building materials have become an urgent problem to be solved for lightweight building materials
