本文总结了几年来混凝土工程抗裂与抗渗的实践经验,表达了作者对商品混凝土的一些思考。混凝土浇筑成型后不可以失水。混凝土失水会形成失水缺陷。由这些缺陷造成的混凝土抗渗性能的降低和开裂,是加快混凝土劣化的两种基本类型。本文提出了完美湿养护的概念,讨论了其对混凝土抗渗、抗裂以及耐久性的重要性;同时也提出了应把不可见裂缝和不可见孔隙缺陷列为控制目标,讨论了其控制方法。 This article summarizes the past few years of concrete engineering anti-cracking and impermeability of practical experience, expressed the author of some commodity concrete. Concrete pouring can not be lost after pouring. Concrete water loss will form a water defect. The impermeability and cracking of concrete caused by these defects are the two basic types of accelerating the deterioration of concrete. In this paper, the concept of perfect wet curing is put forward, and its importance to impermeability, crack resistance and durability of concrete is discussed. At the same time, it is also proposed that invisible cracks and invisible pore defects should be listed as control targets. The control methods .
