高寒地区低温早强耐久性混凝土质量控制探讨

Quality Control Discussion of Low Temperature Early-strength Durable Concrete in Alpine Region

通过对输电线路混凝土基础在负温、缺氧、腐蚀环境下的受害机理进行分析,对负温混凝土浇制时材料的控制、配合比、复合外加剂的配置、施工、养护等技术条件进行了探讨和研究,阐述了高寒地区低温早强耐久性混凝土质量控制的方法和技术,对多年冻土地区输电线路工程混凝土基础的配合比设计和施工起到了一定的指导作用。

The paper makes analysis on suffered mechanism of transmission line＇ s concrete foundation under negative temperature, oxygen lack and corrosion environment, and makes discussion and study on material control, mix proportion, as well as compound additive＇ s configuration, construction and curing during pouring negative concrete, as well as discusses quality control method and technology of low temperature, early-strength durable concrete in alpine region, thus provides certain guidance for concrete foundation＇ s mix proportion and construction of transmission line engineering in permafrost regions.
