摘　　要：冬季的施工环境是较为恶劣的,从混凝土施工来说,早期结构强度达不到要求的情况是较为常见的,这对后续施工会造成较大的影响。若想使得低温产生的影响得到有效控制,必须要将适合的外加剂掺入到混凝土中,这样方可加快凝结的速度。另外,相关人员还要展开更为深入的研究,对混凝土凝结的整个过程进行分析,将各种影响因素突显出来,寻找到切实可行的方法来保证冬季混凝土施工的质量,当前使用较为普遍的是复掺技术。论文主要从冬季混凝土施工的现状出发,对存在的主要问题展开分析,重点对如何使用掺合料进行阐述,对复掺技术的实际应用予以介绍。In winter,the construction environment is relatively bad.From the perspective of concrete construction,it is common that the early structural strength fails to meet the requirements,which will have a greater impact on the subsequent construction.If the effect of low temperature is effectively controlled,a suitable admixture must be added into the concrete,so as to accelerate the setting speed.In addition,relevant personnel should carry out more research to analyze the whole process of concrete setting,highlight all kinds of influencing factors,and find practical methods to ensure the quality of concrete construction in winter.More commonly used at present is the compounding technique.At present,the technology of complex doping is widely used.Based on the current situation of concrete construction in winter,this paper analyzes the main problems,focuses on how to use admixtures,and introduces the practical application of complex admixture technology.
