Preparation method of slag-based geopolymer cementing material and application of slag-based geopolymer cementing material in building materials
The invention provides a preparation method of a slag-based geopolymer cementing material and application of the slag-based geopolymer cementing material in building materials, and belongs to the technical field of building materials. According to the slag-based geopolymer cementing material, slag and fly ash serve as precursors, water glass serves as an alkali activator, the mass ratio of the slag to the fly ash is (5-7): (3-5), the doping amount of the water glass in the precursors is 15-25 wt%, and the modulus of the water glass is 1.0-1.4. Gel products of the slag-based geopolymer cementing material are mutually interwoven and overlapped, so that pores in a matrix can be more effectively filled, the porosity of the matrix is reduced, and a more compact cementing structure is formed, so that the mechanical property of the material is improved, and the slag-based geopolymer cementing material can be further used for preparing road base stabilized macadam, stabilized soil, concrete and other scenes.
本发明提出了一种矿渣基地聚物胶凝材料制备方法与在建筑材料中的应用，属于建筑材料技术领域。本发明的矿渣基地聚物胶凝材料以矿渣和粉煤灰作为前驱体，以水玻璃作为碱激发剂，其中，所述矿渣和粉煤灰的质量比为(5～7)∶(3～5)，所述水玻璃在所述前驱体中的掺量为15～25wt％，所述水玻璃的模数为1.0～1.4。该矿渣基地聚物胶凝材料的凝胶产物相互交织重叠可以更加有效的填充基体内的孔隙，降低基体的孔隙率，形成了更加密实的胶凝结构，从而改善材料的力学性能，可以进一步用于制备公路基层稳定碎石、稳定土及混凝土等场景。
