摘要：

The effect of internal curing on the structural behaviour of large high-performance concrete specimens having different amounts of pre-soaked porous lightweight aggregate was investigated. The results show that the use of lightweight aggregate in high-performance concrete can effectively reduce autogenous shrinkage through improved hydration of cement.
