在现代建筑中,大体积混凝土的工程规模日趋扩大,为确保大体积砼施工质量,除满足强度等级、抗渗要求外,关键要严格控制混凝土在硬化过程中引起的内外温差,防止因温度应力而造成混凝土产生裂缝。本文结合工程实践和科研成果,分析了温度裂缝产生的原因,提出了大体积混凝土结构防止产生裂缝的措施。
In modern buildings, the project scale of large-volume concrete is expanding day by day. To ensure the construction quality of large-scale concrete, in addition to satisfying the strength grade and impermeability requirements, the key is to strictly control the internal and external temperature difference caused by concrete in the hardening process, and to prevent temperature stress. Cause cracks in concrete. In this paper, the causes of temperature cracks are analyzed based on engineering practice and scientific research results. Measure of large-scale concrete structure to prevent cracks is proposed.
