一种多孔轻质地质聚合物水泥及其制备方法
Porous lightweight geopolymer cement was prepared by combining metakaolin, granulated blast furnace slag powder, and composite alkali-activated liquid with waste materials. The self-heating curing by chemical reaction heat solved the problems of high energy consumption, high emissions, and insufficient performance, and realized a lightweight, high-strength, fireproof, and heat-insulating porous cement material.

AI Technical Summary
The production of existing porous cement-based materials relies on high-energy-consuming and high-emission high-temperature calcination processes, making it difficult to achieve the complete solid waste treatment of raw materials and low-carbon and energy-saving preparation. Furthermore, traditional insulation materials cannot simultaneously achieve lightweight, high strength, and excellent thermal insulation performance.
Using metakaolin and granulated blast furnace slag powder as the cementitious matrix, combined with a composite alkali activating liquid, and utilizing industrial and domestic waste, calcium terephthalate whiskers and a diol water-retaining network are generated through the chemical reaction of photovoltaic cutting silicon waste slag and waste polyester plastic powder to achieve self-heating curing and prepare porous lightweight geopolymer cement.
It achieves complete solid waste treatment, reduces production costs and carbon emissions, and produces lightweight, high-strength, fire-resistant, and heat-insulating porous lightweight geopolymer cement, which is suitable for building insulation, heat insulation and filling, and solves the performance deficiencies of traditional materials.
