Lightweight aggregate concrete and normal concrete were prepared, and the creep behaviors were tested by the varying stress creep test at the stress level of 30% together with the shrinkage age test at early age(028d). Results show that lightweight aggregate concrete has less shrinkage, and creep coefficient is 50% that of normal concrete with the same strength at early age. Whereas the creep strain of lightweight aggregate concrete is almost 13 times that of normal concrete at early age.
