底板大体积混凝土施工裂缝的控制

The control of the construction crack of motherboard mass concrete

结合工程实例,从原材料的选用要求和施工配合比两方面介绍了大体积混凝土的配合比设计,并对混凝土温度控制及施工过程进行了介绍,同时对混凝土的测温及其质量检测结果进行了分析,从而有效防止大体积混凝土施工裂缝的产生。

Combined with the project examples,it introduces the design of adapt ratio of mass concrete from the aspects of the select of row material and the adapt ratio of construction,and introduces the temperature control and construction process of concrete.And in the same time it analyses the measure of temperature of concrete and its quality measure solution,so to prevent the generation of construction crack of mass concrete effectively.
