高温下大坍落度混凝土施工裂缝分析与防治

Analysis and Prevention of Cracks in Concrete with High Slump at High Temperature

大坍落度混凝土在高温条件下的施工裂缝问题在现阶段显得尤为突出,已经成为困扰工程施工人员的一大难题,针对这种比较普遍的工程现象,对大坍落度混凝土在高温条件下裂缝出现的原因进行了分析,并提出了一系列有效的防治大坍落度混凝土裂缝出现和开展的措施.这些措施在实际工程中进行应用,取得了不错的效果,迄今为止无裂缝出现,为以后的类似工程提供了一定的借鉴作用.

The construction crack problem of high slump concrete under high temperature is especially prominent at this stage,which has become a difficult problem for the construction workers.In view of this common engineering phenomenon,this paper analyzes the causes of cracks in high temperature condition,and puts forward a series of to prevent and cure the cracks of concrete with large slump.Being applied in practical engineering,these effective measures achieved good results. So far,no cracks appeared which provides a reference for future similar proj ects.
