Abstract：
In order to induce cracking of high performance concrete(HPC) at early age, a non-contacting measurement technology was adopted in this article?郾 Autogenous shrinkage and shrinkage with single side in dry environment of HPC were tested by using the measure technology?郾 The effects of shrinkage reducing agent (SRA), polypropylene fiber（PPF）and different water reducing agents on autogenous shrinkage and shrinkage of HPC with single side in dry environment were discussed?郾 Based on the results of shrinkage test, the slab specimens of HPC were restrained by utilizing the steel frame and the effects of SRA, SRA + PPF etc?郾 on resist-cracking of HPC in dry environment were discussed?郾 The whole anti-cracking effects of these ways, which can both reduce autogenous shrinkage and cracking of HPC, are obtained from high to low: SRA+ polycarboxylate high performance water reducing agent, SRA+ FDN high performance water reducing agent, SRA +PPF, and PPF?郾
