高层建筑泵送混凝土楼板裂缝的控制

Crack control of a high- rise building pumping concrete floor

本文主要从设计、材料、施工角度进行分析,提出采取控制混凝土的收缩应力及温差应力,控制混凝土坍落度,以达到控制混凝土的收缩,控制高层建筑泵送混凝土裂缝的目的。

From three angles, including design materals and construction, the writer expound methods to control contraction stress and thermal stress and concrete slump,which can control concrete contraction and cracks.
