摘要

This paper presents fundamental properties of lightweight aggregate concrete to be applied for pre-casting and pre-stressed concrete slab. The properties of volume change which influences the effective pre-stress are discussed based on instantaneous and long-term tests. The tensile and shear strengths by various tests are also investigated and these properties affect the punching shear strength of slab.
