超高性能混凝土研究与应用进展

为了进一步推动UHPC在实际工程领域的应用,本文从制备过程、力学性能、应用进展对超高性能混凝土基本力学性能研究成果进行了系统的阐述,并设置0％、1％、1.5％、2％、2.5％、3％、4％共7组不同体积的钢纤维掺量进行了试验.试验结果表明,随着钢纤维含量的增加,试块基体的延性有了很大的提高,且抗压强度和抗拉强度均有提高,...

Progress in Research and Application of Ultra High Performance Concrete

In order to further promote the application of UHPC in the field of practical engineering,this paper systematically describes the research results of basic mechanical properties of ultra-high performance concrete from the aspects of preparation process,mechanical properties and application progress,and sets seven groups of steel fiber volume dosage of 0%,1%,1.5%,2%,2.5%,3%and 4%to carry out tests.The test results show that with the increase of steel fiber content,the ductility of the matrix is greatly improved,and the compressive strength and tensile strength are improved,and the optimal content of steel fiber is determined to be 2%.Then,the application status of UHPC in civil engineering field at home and abroad is summarized,and its future is also prospected.
