Abstract

Abstract: Based Oil the concrete hydration-temperature test of the tilsferfloor girders in No.11 and No．12 buildings，Jiazhou garden， the paper studies the characteristic ofthe time-temperature curves during concrete hydration in high-rise building transferfloor， and brings forwardures to avoid cracng by concrete hydration．The data and the successful,experience from the example project is able to be referencedby other similar situation

Key words: hijh-rise building timider flor, Inass concrete, construction, heat of hydration

摘要： 笔者以重庆加州城市花园11、12楼为依托工程，对高层建筑转换层钢筋砼大梁浇筑时水化热特性进行了监测研究，对所测温度变化曲线进行分析，提出了防止水化热裂的措施，所测数据及成功经验可以供类似工程参考
