大体积混凝土由于体积大,混凝土在自然凝固成型的过程中,内部水化热反应变化剧烈,再加之环境温度与混凝土内部温度的差异是混凝土在降温凝结过程中产生一涨一缩,导致混凝土产生裂纹。混凝土裂纹必然影响到结构物的使用功能。有关各方为了缓解裂缝的产生做了大量的实践工作。从施工、设计、裂缝和监测等方面详细分析了裂缝成因,并对当下的混凝土裂缝控制方法进行了相关的改进工作,提出了大量建设性的意见与建议。收到了成效,确保了工程质量。
Large volume of concrete due to the volume of concrete in the natural coagulation process, the internal hydration reaction dramatic changes, coupled with the ambient temperature and the internal temperature difference is the concrete in the cooling condensation process produces a rise and fall, resulting in concrete production crack. Concrete cracks will inevitably affect the structure of the function. All parties concerned have done a great deal of practical work to ease the crack. The causes of cracks were analyzed in detail from the aspects of construction, design, cracks and monitoring, and some corrections were made to the current control methods of concrete cracks. A lot of constructive comments and suggestions were put forward. Received results to ensure the quality of the project.
