摘要
轻骨料混凝土在耐久性、泵送性、收缩和徐变性等方面有着很大的优势,所以这种材料在旧桥改造的过程中被广泛应用。通过对轻骨料混凝土在旧桥改造中的分析,阐述轻骨料在旧桥改造中的应用。
Light -weight aggregate concrete has a great advantage on durability, pumping capacity, contractility and degeneration, so this kind of materials is widely used on the process of old bridge reconstruction. Through the analysis of light - weight aggregate concrete on old bridge reconstruction, the application of lightweight aggregate on old bridge reconstruction is stated.
