| 摘 要： | The grading of lightweight aggregate (LA) and its water content has an effect on the plastic shrinkage cracking of lightweight aggregate concrete (LWAC). Test results show that the water absorption of LA and the water evaporation of the concrete increased with the increment of cubage of LA, but the area of plastic shrinkage cracking of LWAC decreased. Besides, LA with high water content is beneficial to restraining the plastic shrinkage cracking of LWAC.
