混凝土是一种利用多种建筑材料混合制成的脆性材料,由于本身的约束和环境的客观因素导致在桥梁、土木建筑的使用中经常出现混凝土结构裂缝的情况,严重的甚至会腐蚀到建筑内部的钢筋,造成建筑物寿命的缩短。本文针对房建施工中混凝土结构出现的裂缝原因进行分析,并根据裂缝原因提出相应的预防对策。 Concrete is a kind of brittle material made by mixing a variety of building materials. Due to its own constraints and environmental objective factors, cracks in concrete structures often occur in the use of bridges and civil buildings, and even serious corrosion can be caused inside the building Of steel, resulting in shortening the life of the building. In this paper, the causes of cracks in the concrete structures in the construction of houses are analyzed, and the corresponding prevention measures are put forward according to the causes of the cracks.
