| Abstract: | Recently,many concrete structures have appeared cracks of different degrees and different forms at construction and using stage.The cracks causes are complex,and also have many influencing factors.Through several practical engineerings,the characteristics,causes and mending options of typical cracks are discussed,such as floor crack and wall crack in buildings with internal heat preservation in external walls,concrete shrinkage crack in beam in frame,settlement crack and shrinkage crack of floor slab. |
