超高性能混凝土国内进展及性能试验研究

Research on Domestic Progress and Performance Test of Ultra High Performance Concrete

本文综述了超高性能混凝土(UHPC)的发展以及在中国的研究与应用,阐述了超高性能混凝土的配制原理与力学性能,并通过试验初探对比了钢纤维形状及硅灰掺量对UHPC的性能影响。超高性能混凝土是一种新型水泥基材料,相比高性能混凝土强度更高、韧性更大、耐久性更好,目前UHPC已经在国内许多工程获得应用。

In this paper,the development of Ultra High Performance Concret （UHPC） and its research and application in China are reviewed. The preparation principle and mechanical properties of Ultra High Performance Concret are expounded,and the influence of the shape of steel fiber and the amount of silica fume on the performance of UHPC is compared through the test. Ultra High Performance Concret is a new type of cement-based .It has higher strength, greater toughness and better durability compared to high performance concrete. At present, UHPC has been applied in many domestic projects.
