摘要
大体积混凝土温度裂缝控制一直是工程界关注的问题。堆石混凝土单方水泥用量少,水化温升低,在控制大体积混凝土温度裂缝方面体现了独特的优越性。本研究以实际工程为依托,通过试验监测大体积堆石(卵石)混凝土的内部温度变化;经水化热计算分析,得出在进行大体积混凝土工程施工时,采用堆石混凝土施工技术可减少或免除混凝土的温控措施。
How to control cracks which are caused by the temperature changes in massive concrete is concerned by engineers, Rockfilled concrete has unique superiority to controlling cracks in massive the concrete for its construction method. Based on actual projects, through the calculating and measuring of the internal temperature for the massive rock-filled concrete, the study comes to the conclusion that construction by the rock-filled concrete can reduce or waive temperature control.
