Concrete based on waste mud geopolymer and preparation method thereof
The invention provides geopolymer concrete based on waste mud and a preparation method thereof, and belongs to the technical field of geopolymer concrete. The raw materials of the concrete based on the waste mud geopolymer comprise a cementing material, an alkali activator, a mud filter cake, aggregate and water, the cementing material comprises fly ash and slag powder, the mixing amount of the fly ash in the cementing material is 30-60%, the mixing amount of the slag powder in the concrete based on the waste mud geopolymer is 99-200kg/cm < 3 >, and the mixing amount of the alkali activator in the concrete based on the waste mud geopolymer is 100-200kg/cm < 3 >. The mass ratio of the cementing material to the alkali activator to the slurry filter cake to the aggregate is 1: (0.38-0.60): (1.0-1.1): (4.5-4.7), and the initial water-binder ratio of the geopolymer concrete based on the waste slurry is 0.40-0.44. The waste mud is recycled, and the prepared geopolymer concrete based on the waste mud is relatively high in compressive strength, tensile strength and breaking strength, and meets the use requirements of the concrete.
本发明提供了一种基于废弃泥浆地聚合物混凝土及其制备方法，属于地聚合物混凝土技术领域。本发明的基于废弃泥浆地聚合物混凝土原料包括胶凝材料、碱激发剂、泥浆滤饼、骨料、水，其中胶凝材料为粉煤灰和矿渣粉，粉煤灰在胶凝材料中的掺量为30～60％，矿渣粉在基于废弃泥浆地聚合物混凝土中的掺量为99～200kg/cm3，胶凝材料、碱激发剂、泥浆滤饼、骨料的质量比为1：0.38～0.60：1.0～1.1：4.5～4.7，基于废弃泥浆地聚合物混凝土的初始水胶比为0.40～0.44。本发明实现了废弃泥浆的再利用，并且所制备的基于废弃泥浆地聚合物混凝土的抗压强度、抗拉强度和抗折强度都较高，满足混凝土使用要求。
