混凝土塑性裂缝产生原因及防治

为了在实际工程中有效地防治混凝土塑性裂缝的出现，从裂缝产生的原因进行分析，提出对不同类型混凝土构件采用二次抹压或二次振捣加二次抹压相结合的防治措施，并从施工工艺及注意要点两方面进行了阐述，采用上述措施，可使混凝土塑性开裂这个工程中常见的通病得到根除，保证了混凝土耐久性及表面质量。

The producing reasons of plastic cracks of concrete and its precaution

In order to effective prevent the producing of plastic cracks in actual engineering the producing reasons of plastic cracks are analyzes in this article. For different concrete components precautions as secondary plastering and compacting and the combining method of secondary plastering and compacting with secondary ramming and vibrating are proposed. at the same time the construction technology and key points needing attention are elaborated. Through those measures the plastic cracks are eliminated and the durability and surface quality are ensured.
