东北寒区热电厂房冬季混凝土施工防裂措施研究

Research on crack prevention measures for winter concrete construction of thermal power plant in northeast cold region

针对东北天气寒冷缩短建设工程混凝土施工的情况,以实际工程为例,对冬季施工混凝土易出现裂缝的成因加以分析,从原材料选择、混凝土配置、施工现场生产组织与养护方式方面入手,有针对性地提出防治裂缝病害的措施,延长施工时间的同时,保证混凝土建筑物的施工质量。

In view of the situation of concrete construction in northeast China which is shortened by cold weather,taking actual projects as an example,this paper analyses the causes of concrete cracks in winter construction.Starting from the selection of raw materials,concrete allocation,production organization and maintenance mode of construction site,it puts forward the measures to prevent and control cracks,prolongs construction time and ensures mixing.
