Preparation method and application of coagulant for cement combined castable
The invention belongs to the technical field of building materials, and particularly relates to a preparation method of a coagulant for a cement-bonded castable. The preparation method comprises the following steps: (1) adding a metal chloride salt solution into cement, and uniformly stirring and mixing to obtain mixed slurry; (2) carrying out suction filtration on the mixed slurry prepared in the step (1) to obtain a filter cake; sequentially freezing and drying the filter cake under a vacuum condition to obtain powder; and (3) uniformly mixing the powder prepared in the step (2) with a grinding aid, and grinding to obtain the coagulant for the cement combined castable. The prepared coagulant not only can shorten the coagulation time of the calcium aluminate cement combined castable, but also can improve the demolding strength and drying strength of the cement combined castable, greatly improves the production efficiency and economic benefits of cement combined castable prefabricated parts, and has great commercial application value.
本发明属于建筑材料技术领域，具体涉及一种水泥结合浇注料用促凝剂的制备方法。上述制备方法的步骤为：（1）将金属氯化盐溶液加入水泥中，搅拌混匀，得到混合浆料；（2）将步骤（1）制备的混合浆料抽滤，得到滤饼；将滤饼在真空条件下依次进行冷冻、干燥，得到粉料；（3）将步骤（2）制得的述粉料与助磨剂混合均匀后进行研磨，即得水泥结合浇注料用促凝剂。本发明制备的促凝剂不仅能够缩短铝酸钙水泥结合浇注料的凝固时间，同时还能提高水泥结合浇注料的脱模强度和干燥强度，极大地提高了水泥结合浇注料预制件的生产效率和经济效益，具有极大的商业应用价值。
