混凝土冬期施工

大量工程实践表明,寒冷地区在冬季施工时,混凝土表面极易丧失水分,影响混凝土强度的发展。为了保证冬期施工混凝土的质量,在负温环境中要创造各种可能的施工措施及养护条件,使新浇筑的混凝土得以正常硬化并达到设计要求的强度等级。

Introduction tothe concrete winter construction

a large number of engineering practice shows that cold area in winter construction, the concrete surface to water loss, affect the concrete strength. In order to guarantee the quality of winter concrete construction, in the negative temperature environment in order to create a variety of possible construction measures and curing conditions, make the new pouring concrete to normal hardening and strength grade to meet the design requirements
