Shrinkage-resistant geopolymer cementing material and preparation method thereof
The invention provides an anti-shrinkage geopolymer cementing material and a preparation method thereof, the anti-shrinkage geopolymer cementing material is a new anti-shrinkage geopolymer cementing material, slag is mainly used as a raw material, coal gangue powder with a potential hydraulic material is used as an admixture, and a low-dosage expanding agent is selected to improve the anti-shrinkage performance of the material. The geopolymer cementing material with excellent shrinkage resistance and mechanical properties is obtained, and the problems that in the prior art, the shrinkage rate of geopolymers is large, coal gangue is comprehensively utilized, and the energy consumption of extraction and synthesis of common expanding agents is high are effectively solved.
本发明提供了一种抗收缩型地聚物胶凝材料及其制备方法，为新的一种抗收缩型地聚物胶凝材料，主要以矿渣为原料，采用具有潜在水硬性材料的煤矸石粉末作为掺合料，选择低掺量膨胀剂提高材料抗收缩性能，得到了具有优异抗收缩性能和力学性能的地聚物胶凝材料，有效解决现有技术中地聚物收缩率大和煤矸石综合利用问题以及常用膨胀剂萃取、合成能耗高的问题。
