对公路工程冬季混凝土施工技术见解对公路工程冬季混凝土施工技术见解 摘要: 冬季施工是指根据当地多年气温资料,室外日平均气温连续 5d 稳定低于 5℃时混凝土工程的施工
新浇筑的混凝土在养护初期遭受冻结,不仅影响混凝土强度的正常增长,使其不能达到设计强度,而且严重影响混凝土的质量及耐久性,作者就自己的施工经验剖析混凝土受冻的原因,介绍了混凝土冬季施工的方法
关键词:混凝土;冬季施工 ;技术 Abstract: The winter construction refers to according to the local data of the temperature of the concrete construction for many years, the average temperature of the outdoor consecutive 5D stable below 5℃
The new pouring concrete subjected to freezing in the maintenance period, not only affect the normal growth of the strength of concrete, so that it can not reach the design strength, but also seriously affect the quality and durability of concrete, the author analyzes the reason of frozen concrete construction experience, introduces the method of concrete construction in winter
