在大体积混凝土中,对温度的控制是十分的重要的。因为,在施工过程中,混凝土常常会出现难以克服的裂缝问题,影响到整个施工项目的整体的完成水平。而且开裂情况的出现,对工程建筑物的一个使用寿命会产生巨大的影响。而且在施工的工作当中,温度的变化对建筑结构的一个承受力的态势存在着十分明显的影响。在施工过程当中出现最多的就是混凝土裂缝。裂缝问题的出现,不仅会降低建筑物的抗压能力,而且会使得钢筋暴露在外面,造成钢筋的生锈,混凝土的碳化,从而降低所有材料的使用寿命,影响到建筑物的安全问题。因此,要严格对待混凝土的裂缝问题,对症下药,消除安全隐患。
In mass concrete, the temperature control is very important. Because, in the construction process, often difficult to overcome cracks in concrete, affecting the overall completion of the construction project level. And the emergence of cracking, the life of the engineering buildings will have a huge impact. And in the construction work, the change of temperature has a very obvious influence on a bearing capacity of the building structure. Concrete cracks occur most frequently during construction. The emergence of cracks not only reduces the compressive capacity of the building, but also exposes the steel bar outside, resulting in the rusting of reinforcing steel and the carbonization of concrete, reducing the service life of all materials and the safety of buildings. Therefore, we must strictly treat the concrete crack problem, the right medicine, eliminate security risks.
