高质量地生产混凝土制品,延长其使用寿命,使其在实际使用条件下能抵抗外部环境的侵蚀和破坏,长期保持其强度和完整性,对铁路工程建设有着重要意义。文章首先分析了影响混凝土耐久性的各种可能的因素,然后从混凝土原材料的选择、配合比的优化、外加剂的掺用,搅拌工艺和成型设备的改进,以至蒸养设施和制度的完善提出了一系列建议。
High-quality production of concrete products, extending its service life, making it resistant to external environmental erosion and damage under actual conditions of use, maintaining its strength and integrity for a long time, is of great significance to the construction of railway projects. The article first analyzes the various possible factors that affect the durability of concrete, and then from the selection of concrete raw materials, the optimization of the mix ratio, the admixture of admixtures, the improvement of mixing process and molding equipment, and the improvement of steam curing facilities and systems. A series of suggestions.
