摘要: 重庆江津观音岩长江大桥现浇桥面湿接缝采用补偿收缩混凝土。针对不同类型、不同掺量的膨胀剂进行强度和限制膨胀率的正交试验,从而选择出适用于该桥的膨胀剂类型、掺量以及膨胀混凝土的配合比。
关键词: 补偿收缩混凝土, 限制膨胀率, 配合比
Abstract: The shrinkage-compensating concrete is adopted in Chongqing Jiangjin Guanyinyan Yangtze River Bridge wet cast-in-place bridge expansion joints.Aiming at different types and mixing amount of expanders,the orthogonal tests on strength and restrictions on expansion are carried out.Consequently,the type of expanders,the mixing amount and the mix ratio of expansive concrete suitable for this bridge are selected out.
Key words: shrinkage-compensating concrete, restrictions on expansion, mix ratio
