Abstract

In this study, the influence of three types of pre-wetted lightweight aggregates (PLWA) on the shrinkage of concrete was experimentally investigated, in which the variation of the volume fractions and moisture content was considered. The results show that the shrinkage of concrete after age 150d increased with increasing the PLWA content, while the change was not linear. It was found that the use of PLWA increased the shrinkage at 240d due to the significant increase in the shrinkage deformation during the age of 28d to 90d, which was supposed to be caused by the internal curing.
