摘要
厚度不大的混凝土墙体也会产生较大的水化热温升,导致墙体内外温差过大,引起温度裂缝。此外,温度过高,也会加快墙体混凝土干燥收缩的早期发展,从而更容易引起收缩裂缝。在试验的基础上,分析了温度对混凝土墙体早期开裂的影响,给出了计算建议。
The concrete wall with thin thickness also can produce the great hydration heat temperature and, cause a great temperature difference between inside and outside of the wall and, lead to the temperature crack. In addition, the high temperature also can speed up the early development of the wall concrete drying shrinkage, thus easier to cause the contraction crock. Basing on the experimental data, the article analyzes the temperature influence on the concrete wall early stage crack and, suggests the computation.
