摘　　要：本文通过工程实例对混凝土施工过程中C25泵送混凝土含气量难以控制、和易性较差、拆模后混凝土表面有蜂窝麻面,及在高温时段混凝土浇筑过程中,混凝土失水快、易风干、容易形成"硬结壳"、出现假凝现象等原因进行了分析,并提出了解决途径。During the concrete construction, it is difficult to control air content of C25 pumping concrete. C25 pumping concrete has poor workability and honeycomb pitting surface on the surface of the concrete after form stripping. Apart from that, during the process of concrete placing at high temperature, concrete loses water fast and is easy to be dried, which makes it form hard cnast easily and produce false condensation. The paper analyses the causes of the phenomenons above and proposes solutions.
