Several experimental investigations were conducted on the autogenous shrinkage and creep performances of two types of designed self-compacting lightweight concrete (SCLC). In order to explore the difference in long-term performance between SCLC and normal aggregate concrete, normal aggregate self-compacting concrete (SCC) and normal concrete (NC) are also designed in this study. The results indicate that the designed SCLC exhibits lower autogenous shrinkage at early age, even slight expansion during the first 10 days. After 6 months, the autogenous shrinkage of SCLC increases nearly equal to those of normal aggregate concrete. Compared with the reference concretes NC and SCC, the 360-day creep coefficient of SCLC is lower, but the specific creep is higher. It is also found that long-term creep coefficient and specific creep decrease with the increase of compressive strength of SCLC.

Non-structural cracking of concrete is a serious problem and the underlying phenomena, namely, shrinkage and creep, need to be better understood. Much research has been devoted to this complex problem. However, despite major successes, the phenomenon of autogenous shrinkage is still far from being fully understood. The paper discusses the main aspects of concrete shrinkage, with a focus on autogenous shrinkage, which are especially important in low water/binder ratio concrete. These aspects include the theories of physical mechanism, prediction models and future research trends. Shrinkage of concrete due to moisture changes, which result in surface and capillary tension, was reviewed. The mechanisms often cannot be directly linked to the macroscopically observed dilatation/contraction. An overview of recent model developments is also presented.
