Aqueous cement hydration rate regulation and control material and preparation method thereof
The invention provides an aqueous cement hydration rate regulation and control material and a preparation method thereof; the aqueous cement hydration rate regulation and control material is a derivative obtained by reacting an aldehyde group of reducing sugar with an amino group of an amino reactant; the preparation method is a simple aqueous solution reaction method. The aqueous solution obtained by the method has a good cement hydration rate regulation effect on the premise of not influencing the final total heat release of cement, so that the hydration heat release of the cement is more stable, meanwhile, the preparation process is simple, the drying of a solid finished product and the use of an organic solvent are reduced, and the theme of green chemistry is met.
本发明提供一种水剂水泥水化速率调控材料及其制备方法，本发明所述水剂水泥水化速率调控材料是将还原性糖的醛基和氨基反应物的氨基进行反应，得到的衍生物；其制备方法是简单的水溶液反应的方法，该方法得到的水溶液在不影响的水泥最终总放热量的前提下，有较好的水泥水化速率调控作用，使水泥水化放热更平稳，同时该制备工艺简单，减少了固体成品干燥和有机溶剂的使用，符合绿色化学的主题。
