底板大体积混凝土浇筑裂缝控制

Construction Practice of Large Bulk Concrete Pour for the Base Slab

温度差是引起大体积混凝土裂缝的主要原因之一。在大体积混凝土基础工程中,优化混凝土配合比设计以控制温度差为目标,采用降低水泥用量,不仅使混凝土达到强度要求,而且未产生裂缝和渗漏,达到设计要求。

Temperature difference is one of the most reasons of crack in the large bulk concrete. The temperature difference control is the aim of large bulk concrete mix ratio design and it adopts reducing the cement to achieve not only the strength request, but also no craek and leakage, and satisfy the design demand.
