摘要
研究了用于某钢管混凝土拱桥的细颗粒自密实混凝土配合比设计,对选定配合比的混凝土进行了抗压强度和弹性模量随龄期变化的测试试验。结果表明细颗粒自密实混凝土能满足钢管混凝土拱桥的施工性能和基本力学性能。
The design of mix proportion of small diameter aggregates self-compacting concrete （SCC） was studied,and the compression strength and the elastic modulus of the SCC mixtures with a certain mix proportion was tested.The results show that the SCC mixtures can be satis- fied the workability and the mechanical properties of the concrete filled steel tubes.
