摘　　要：水泥是混凝土最重要的胶凝材料,对混凝土拌合物性能和各项力学指标起着决定性作用.通过试验,分析了不同水泥温度对混凝土拌合物性能的影响和作用机理,并提出了解决措施.解决水泥温度过高,最有效的措施是给水泥一定的陈放时间,使水泥温度自然冷却到室温,然后再输送至水泥储备粉料罐中.因水泥温度高引起混凝土坍落度、扩散度损失过大影响混凝土浇筑时,可在浇筑地点,进行二次添加减水剂.Cement is the most important cementitious material for concrete,playing a decisive role in the performance and various mechanical indicators of concrete mixtures.Through experiments,this paper analyzes the impact and mechanism of different cement temperatures on the performance of concrete mixtures,and proposes solutions.The most effective measure to solve the problem of high cement temperature is to give the cement a certain aging time,allowing the cement temperature to naturally cool to room temperature,and then transport it to the cement reserve powder tank.When the loss of slump and diffusion of concrete caused by high cement temperature affects the pouring of concrete,a second addition of water reducing agent can be carried out at the pouring site.
