风冷骨料作为夏季降低大坝混凝土出机口温度的有效措施,近年来已应用于大中型水电工程混凝土施工,并取得良好的效果.如何提高风冷骨料的冷量利用率,节省混凝土预冷费用,日益受到人们的关注.本文通过对万安工程风冷骨料实测资料的分析,找出了影响冷量利用的有关因素,并提出相应的改进措施. Air-cooled aggregate, as an effective measure to reduce the temperature at concrete exit of dam, has been applied to the construction of large and medium hydropower projects in recent years and achieved good results. How to improve the utilization of air-cooled aggregate and save concrete The cost of pre-cooling is getting more and more attention from people.Through the analysis of the measured data of the air-cooled aggregate of Wanan Project, the relevant factors that affect the utilization of cold capacity are found and the corresponding improvement measures are put forward.
