High performance concrete is of many excellent characteristics.However,its fluidization and high strength may advance a cracking tendency of a structure,which is contrary to the expected design target -durability.As a technical measure of shrinkage compensation,expansion additive to be mixed with the concrete may be helpful to improve the quality of high performance concrete.%高性能混凝土具有许多优良性能，但其流态化和高强化也会使结构发生裂缝的倾向增大，与耐久性的主要设计目标相悖。对此掺入膨胀剂作为补偿收缩的技术措施。掺入膨胀剂对高性能混凝土的性能有益无害。
