Abstract
This paper presents the results of structural laboratory testing of large prismatic high-performance concrete (HPC) specimens under restrained shrinkage and tensile creep. The structural behaviours of concrete specimens having different amounts of pre-soaked structural lightweight aggregate (SLWA) are compared. The results show that the use of SLWA in HPC can effectively prevent autogenous shrinkage when compared to the control HPC, which exhibited a large shrinkage strain of ?260 µå within 24 hours. The quantities of SLWA used in HPC (up to 20% sand replacement) did not adversely affect the slump, air content, strength, or modulus of elasticity.
