Abstract
In recent years, new types of artificial lightweight aggregate with superior water absorption properties have been developed. The application of these high-performance lightweight aggregates is very interesting, because the improvements of the workability, strength and durability of lightweight aggregate concrete can be expected. However, few studies have been carried out on the shrinkage of high-performance lightweight aggregate with low water cement ratio.
Factors influencing shrinkage mechanisms of high-performance lightweight aggregate concrete, such as mix proportion, curing condition have been experimentally studied. The relations between autogenous shrinkage and drying shrinkage have been considered for this lightweight aggregate concrete.
