摘　　要：对某在建工业厂房混凝土结构质量进行了检测,发现混凝土强度偏低、现浇板开裂渗漏等病害,分析了泵送商品混凝土冬季施工病害产生的原因,评估了混凝土强度、裂缝和冻融深度,提出了针对性的工程防治措施,保证了后续工程建设的质量。The concrete structure quality of an industrial building was detected, and some construction diseases such as low concrete strength, cracking and leaking of slabs were found. The reasons of pumping premixed concrete diseases in winter construction are analyzed. The concrete strength, cracks and frozen depth are assessed. In addition, some pertinence engineering measures are put forward to ensure the quality of follow-up project construction.
