摘要
通过原材料选取、配合比设计和热工计算等一些技术准备,制定大体积混凝土冬季施工温度控制技术方案,并在施工中观测热水温度和混凝土的浇注温度、内部温度及表面温度。实践证明,所采取的温控措施对消除大体积混凝土的收缩裂缝效果明显。
By some technical preparation such as selecting and testing raw materials,ratio experiments and hot work calculation,the author discusses the measure of controlling the temperature of the mass concrete construction in winter and the maintenance approaches of concrete based on calculation and observing in practice the temperature of hot work and that of concrete pouring,and the inside temperature and surface temperature.
