入模温度是影响大体积混凝土内部温度场变化的重要因素之一。采用水化微量热仪，研究了入模温度（15、25、35℃）对纯水泥体系、水泥-粉煤灰体系、水泥-矿粉体系及矿物掺合料双掺体系下的水化放热特性影响规律。研究结果表明，提高入模温度对于胶凝材料体系的水化放热反应促进效果明显，掺加粉煤灰和矿粉可以降低混凝土的放热量和放热速度，大体积混凝土在满足混凝土设计强度的条件下，配合比设计应当尽量降低水泥及矿粉的用量，同时降低浇筑施工时的入模温度。

Molding temperature is an important factors which affect the temperature field of massive concrete structures in engineering practice. Used hydration calorimetry,the influences of molding temperature (15、25、35℃) to hydration heat release characteristics that under pure cement system、cement-fly ash system and complex cementitious system was researched. Research results show that ,increasing molding temperature accelerate the hydration reaction of binding material. With the cement relativecontent increased ,the rate of heat liber-ation and heat release of binding material system are improving. mass concrete should try to control the cement and slag powder dosage , and reduce the molding temperature in construction,while the the strength of concrete is reaching the standard.
