摘要：研究了冻融循环、干湿循环、冻融循环+干湿循环、冻融-干湿耦合循环对不同替代率废玻璃骨料混凝土耐久性能的影响。结果表明：与未冻融、未干湿试件相比，经历冻融循环、冻融循环+干湿循环、冻融-干湿耦合循环试件的抗压强度降低、质量损失率增大，而经历干湿循环试件的抗压强度提高、质量损失率减小；不同损伤机制对废玻璃混凝土耐久性能的影响程度由小到大顺序为干湿循环<冻融循环+干湿循环<冻融循环<冻融-干湿耦合循环。 Abstract: The effects of freeze-thaw cycle, dry-wet cycle, freeze-thaw cycle + dry-wet cycle and freeze-thaw and dry-wet coupling cycle on the durability of concrete with different waste glass aggregate replacement rates were studied. The results show that compared with the no freeze-thaw and no dry-wet specimen, the compressive strength of the specimen subjected to freeze-thaw cycle, freeze-thaw cycle + dry-wet cycle, and freeze-thaw and dry-wet coupling cycle decreases and the mass loss rate increases, while the compressive strength of the specimen subjected to dry-wet cycle increases and the mass loss rate decreases. The degree of the influence of different damage mechanisms on the durability of waste glass concrete is in the order of dry-wet cycle < freeze-thaw cycle + dry-wet cycle < freeze-thaw cycle < freeze-thaw and dry-wet coupling cycle.

Abstract: The effects of freeze-thaw cycle, dry-wet cycle, freeze-thaw cycle + dry-wet cycle and freeze-thaw and dry-wet coupling cycle on the durability of concrete with different waste glass aggregate replacement rates were studied.

The degree of the influence of different damage mechanisms on the durability of waste glass concrete is in the order of dry-wet cycle < freeze-thaw cycle + dry-wet cycle < freeze-thaw cycle < freeze-thaw and dry-wet coupling cycle.
