摘　　要：高性能混凝土是以高耐久性为设计目标而发展起来的。随着混凝土技术的发展 ,高性能混凝土已具有许多优良性能 ,但其自身的变形性能尤其是收缩裂缝则有悖于其高耐久性的设计目标。对此本文分析阐述了高性能混凝土的结构特点和变形性能 ,并提出了对不利变形的控制技术 。High performance concrete has been developing towards the design target of high durability.Today high performance concrete is of many excellent characteristics as concrete technology is developing.However,the deformation of high performance concrete is contrary to the expected target of high durability.This paper summarizes the structure and deformation characteristics of high performance concrete,and presents some technologies to control the unfavourable deformation.This is active and helpful to improve the quality of high performances concrete.
