Temperature shrinkage crack

Temperature and shrinkage crack of huge concrete can destruct concrete structure, so it is important to control the crack.

大体积混凝土结构的温度与收缩裂缝对混凝土结构具有破坏作用，控制裂缝的产生，十分重要。

The designer can set post-pouring belt, using UEA con- crete and designing pre-stressing concrete structure to avoid the crack caused by temperature and shrinkage.

超长混凝土结构的设计和施工中可以采取设置后浇带、采用微膨胀——补偿收缩混凝土或设计无粘结预应力混凝士结构来防止温度收缩裂缝的产生。
