Cement hydration temperature rise inhibitor as well as preparation method and application thereof
The invention discloses a cement hydration temperature rise inhibitor and a preparation method and application thereof, and belongs to the technical field of building material admixtures, the cement hydration temperature rise inhibitor comprises the following components by mass: 30-70% of a hydration temperature rise inhibition component, 20-50% of an early strength component, and 10-40% of an organic acid; the hydration temperature rise inhibition component is a starch derivative, and the early strength component comprises at least one of acetate, thiocyanate, nitrate, nitrite and benzoate. Through the synergistic effect of the hydration temperature rise inhibiting component, the early strength component and the organic acid, on the basis of not influencing the hydration temperature rise inhibiting effect, the delayed coagulation of the hydration temperature rise inhibiting component is remarkably reduced, and no negative influence is caused on the working states of cement paste, mortar and concrete.
本发明公开一种水泥水化温升抑制剂及其制备方法和应用，属于建筑材料外加剂技术领域，一种水泥水化温升抑制剂，包括以下质量百分比的各组分：水化温升抑制组分30～70％，早强组分20～50％，有机酸10～40％；所述水化温升抑制组分为淀粉衍生物，所述早强组分包括醋酸盐、硫氰酸盐、硝酸盐、亚硝酸盐、苯甲酸盐中的至少一种。本发明通过水化温升抑制组分、早强组分、有机酸三者之间的协同作用，在不影响其水化温升抑制效果的基础上，不仅显著减少了水化温升抑制组分的缓凝，并且对水泥净浆、砂浆和混凝土的工作状态无负面影响。
