混凝土裂缝是混凝土建筑物主要的老化病害之一。尽管在施工中采取了各种措施,但裂缝仍然时有出现,主要原因是,人们对混凝土的温度应力注意不够。在大体积混凝土浇筑中,温度控制具有重要意义,这主要是由于两方面的原因:首先,施工中,混凝土常常出现温度裂缝,影响到结构的整体性和耐久性:其次,在运转过程中,温度变化影响着结构的应力状态。本文就施工中混凝土裂缝的成因和处理措施做一探讨。
Concrete cracks are one of the major aging diseases in concrete buildings. Although various measures have been taken during the construction, cracks still occur frequently, mainly because people pay insufficient attention to the temperature stress of concrete. In mass concrete pouring, temperature control is of great significance, mainly due to two reasons: First, the construction of concrete often appear temperature cracks, affecting the integrity of the structure and durability: Second, in the course of operation, Temperature changes affect the structural stress state. This article on the construction of concrete cracks causes and treatment measures to do a discussion.
