试论混凝土裂缝的形成原因及防治措施

On the Reasons for the Formation of Cracks in Concrete and Control Measures

混凝土是一种由砂石骨料、水泥、水及其他外加材料混合而成的非均质脆性材料。由于裂缝的存在和发展通常会使结构构件内部的钢筋产生腐蚀,降低构件的承载能力、耐久性及抗渗能力,影响建筑物的外观、使用寿命,严重的将降低结构安全性,甚至威胁到人民的生命、财产安全。

Concrete is a gravel aggregate, cement, water and other materials, plus a mixture of heterogeneous brittle materials. Due to the existence of cracks and structural components will usually develop within the corrosion of steel produced, to reduce the carrying capacity of components, durability and impermeability to influence the appearance of the building, service life, will reduce the serious security structure, thus threatening the People＇s lives and property safety.
