裂缝控制技术在大体积混凝土工程中的应用

Application of Crack Control Technology in Mass Concrete Constructions

文章以包头市某大型筏板混凝土基础工程为例,根据其结构特点,精心选取原材料,优化混凝土的配合比,并通过不同的气候变化制定科学的施工方案,最后对该基础大体积混凝土的温度变化进行实时的温度监控,利用温度变化的特点及时调整控制措施,满足混凝土的内外温差的工程要求,保证该工程顺利施工。

In the paper, it is introduced the raw materials are carefully selected, the mix proportion of concrete is opti- mized based on the structural characteristics of a foundation engineering with large raft concrete in Baotou as well as its sci- entific construction scheme is constituted based on different climate changes. The control measures are adjusted in good time based on the characteristics of temperature changes for mass concrete of the foundation through real - time temperature monitoring,which could meet the engineering requirements for temperature difference between inside and outside concrete to guarantee smooth constructions.
