本文介绍了国税大厦塔楼核心筒承台大体积混凝土的浇筑,采用双掺技术、延长混凝土初凝和终凝时间以及对混凝土进行保温和测温等措施有效地控制混凝土内外温差,避免了因温差应力产生的温度裂缝。
In this paper, the pouring of large volume concrete of the core tube cap of the tower of Guoshui Tower is introduced. The double-doped technology is adopted to extend the initial and final setting time of concrete and to insulate and measure the temperature of concrete so as to effectively control the temperature difference between inside and outside the concrete, The resulting temperature cracks.
