摘　　要：混凝土以其抗压强度高、耐久性能好和可塑性强等优点,在实际生产生活中得到广泛应用,但由于其组成材料的特殊性以及施工过程的复杂性使得其存在一定的缺陷。根据混凝土缺陷的特征和特征尺寸将混凝土缺陷分为宏观缺陷、细观缺陷和微观缺陷,介绍了混凝土缺陷常用的检测方法、研究方法等,提出应从改进施工技术、改进混凝土材料等方面来降低混凝土缺陷出现的概率。The concrete is widely used for its capability of anti-pressure, durability and changeability, but it owns much blemish for the special of its material and the complexity of the construction process.According to the characteristic and the size of the concrete blemish, the concrete blemish could be fallen into the macro-blemish,meso-blemish and micro-blemish,etc.This paper presents the detection method and the study method for the concrete blemish.The purpose of study the concrete blemish is to lower the concrete blemish, and this paper presents two methods improve the technique of the construction process and the concrete＇s material, etc.
