中文摘要：

以徐变度和干燥收缩应变为评价指标,对高强自密实混凝土与普通泵送混凝土进行徐变和收缩特性研究,并分析其与混凝土配合比之间的联系。研究表明：混凝土的徐变度随其强度等级的提高而降低,同样强度等级的自密实混凝土比普通泵送混凝土的徐变度大。研究表明：开始加载龄期延长可降低混凝土的徐变度,高强混凝土的干燥收缩规律与其徐变类似,凡是使徐变增大的因素也会使混凝土的干燥收缩增大;掺加高吸水性树脂的高强自密实混凝土的早期徐变度增长快,但是后期徐变发展速度明显降低,表明其可改善高强混凝土结构的长期变形性能。

英文摘要：

The creep and dry shrinkage of high strength self-compacting concrete was studied with the evaluation indicators of creep degree and shrinkage strain. The influence of their mix proportion was discussed. The creep degree of concrete decreases with the increase of strength of concrete and the prolongation of the loading start time.The creep degree of self-compacting concrete is higher than ordinary concrete at same strength class. The dry shrinkage behavior of high strength concrete is similar to its creep. All factors which enhance the creep of concrete can increase its dry shrinkage. The creep of high strength self-compacting concrete with super-adsorptive polymer（ SAP） develops fast in early age but decreases quickly in later age. Therefore,the long term deformation behavior of high strength concrete structure can be improved.
