本文介绍了高性能混凝土双向和三轴受压试验的研究结果。这些实验是由伺服液压致动器进行的。应力比在致动器的负载能力的极限内是可变的。为了消除加载表面上的约束，使用钢刷将载荷从致动器直接传递到试样。边长为100 mm（3.96 in.）的立方体试样在所有的双向和三轴试验中使用。对三种不同等级的混凝土进行了检测。混凝土的平均圆柱形抗压强度分别为55.5、85.0和93.1 MPa（8.05、12、33和13.50 ksi）。
This paper presents research results of bi- and triaxial compressive tests on high performance concrete. These experiments were performed by a servo-hydraulic actuator. The stress ratios were variable in the limit of the load capacity of the actuator. In order to eliminate the restraint on the loading surface steel brushes were used to transfer the load from the actuator directly to the specimen. Cubic specimens with an edge length of 100 mm (3.96 in.) were used in all bi- and triaxial tests. Three different concrete grades were examined. The mean cylindrical compressive strength of the concretes were 55.5, 85.0 and 93.1 MPa (8.05, 12,33 and 13.50 ksi), respectively.
