混凝土是一种由砂石骨料、水泥、水及其他外加材料混合而形成的非均质脆性材料,是现代工程结构的主要材料,广泛应用于各类建筑工程,然而由于种种主客观因素影响,在混凝土施工过程中,常常会出现各种所谓质量通病,严重影响了工程质量,甚至危及结构安全。 Concrete is a kind of non-homogeneous and brittle material formed by mixing sand aggregate, cement, water and other extra materials. It is the main material of modern engineering structure and is widely used in various construction projects. However, due to various subjective and objective factors In the process of concrete construction, various kinds of so-called common quality problems often occur, which seriously affect the quality of the project and even endanger the safety of the structure.
