冬期混凝土综合蓄热法养护施工实例分析

Case Study on the Winter Concrete Maintenance and Construction with Comprehensive Method of Heat Accumulation

通过冬期施工的典型实例,介绍了混凝土采用综合蓄热法养护施工的方法,探讨了采用商品泵送混凝土综合蓄热法养护施工的热工计算,对出罐和入模温度、混凝土养护期间测温周期及期限给出了明确标准,介绍了如何分析混凝土测温结果,使冬期施工质量控制有章可循。

Through the typical cases of winter construction,this paper introduces the comprehensive method of heat accumulation for the concrete maintenance and construction,probes into the thermo-technical calculation of the maintenance and construction with comprehensive method of heat accumulation for commercial pumping concrete,puts forward the clear standards for the tank-outting temperature and casting temperature of concrete,and temperature detecting cycle and time limit in concrete maintenance period,and introduces how to analyze concrete temperature detecting results, making the quality control of winter construction have rules to follow.
