混凝土基体龄期对水泥基渗透结晶防水涂料性能的影响
|
摘要
在相同的测试条件下,通过吸水率试验对比不同混凝土基体龄期的防水性能,并通过扫描电子显微镜观察不同深度的混凝土基体内部结晶状况。结果表明:随着混凝土基体龄期的延长,基体吸水率逐渐变小;吸水率的变化主要是基体内部生成大量的不溶于水的结晶体造成的。
Under the same test conditions,this article tests the waterproof performance at different concrete matrix age through water absorption contrast experiment, and the internal crystallization conditions of concrete matrix with different depth were observed through the scanning electron microscope. The results show that the absorbency of concrete matrix decreases with the in-creasing of age. The change of absorbency is mainly caused by the formation of a large number of insoluble crystals in the ma-trix.
