Mass concrete hydration heat inhibitor as well as preparation method and application thereof
The invention discloses a mass concrete hydration heat inhibitor as well as a preparation method and application thereof, and belongs to the technical field of concrete admixtures. The hydration heat inhibitor comprises a dissolution heat absorption material, a temperature control heat absorption material, an intelligent heat control material and a hydration reaction adjusting material; wherein the dissolving heat absorption material comprises at least one of calcium nitrate, ammonium nitrate and potassium nitrate; the temperature control heat absorption material comprises sodium thiosulfate, paraffin and barium hydroxide octahydrate; the intelligent heat control material is obtained by wrapping a dissolved heat absorption material with polyethylene glycol; the hydration reaction adjusting material is calcium complexing type sulfonated dextrin. According to the mass concrete hydration heat inhibitor, under the combined action of the dissolving heat absorption material, the temperature control heat absorption material, the intelligent heat control material and the hydration reaction adjusting material, the hydration heat of mass concrete can be regulated and controlled step by step, the hydration heat of the mass concrete is remarkably reduced, and temperature cracks of the mass concrete are effectively controlled.
本发明公开了一种大体积混凝土水化热抑制剂及其制备方法和应用，属于混凝土外加剂技术领域。所述水化热抑制剂包括溶解吸热材料、温控吸热材料、智能控热材料和水化反应调节材料；其中，所述溶解吸热材料包括硝酸钙、硝酸铵、硝酸钾中的至少一种；所述温控吸热材料包括硫代硫酸钠、石蜡和八水合氢氧化钡；所述智能控热材料由溶解吸热材料经聚乙二醇包裹后得到；所述水化反应调节材料为钙络合型磺化糊精。本发明的大体积混凝土水化热抑制剂在溶解吸热材料、温控吸热材料、智能控热材料和水化反应调节材料的共同作用下，可对大体积混凝土的水化热实现逐级调控，显著降低大体积混凝土的水化热，有效控制大体积混凝土的温度裂缝。
