中文摘要：

为研究高强高性能混凝土力学性能,设计6组强度等级在C50～C80的高强高性能混凝土进行标准试验。通过试验,测得高强高性能混凝土立方体抗压强度、轴心抗压强度、抗拉强度、弹性模量及泊松比等性能指标,分析上述性能指标与抗压强度之间的相互关系,并结合已有试验资料,提出合理的统计计算式。

英文摘要：

To study the mechanical property of high-strength and high-performance concrete, standard specimens of C50-C80 high-strength and high-performance concrete were designed for standard tests.By this test, the cube compressive strength, axial compressive strength ,tensile strength ,elastic modulus and Poisson＇s ratio etc were studied.The relationship of above performance indicators was analyzed, and the statistical formulas for various performance indicators were proposed based on the existing experimental data and test results.
