| 摘 要： | 对掺粉煤灰和矿粉的高性能混凝土试件进行了受压性能试验研究,考虑了不同粗骨料种类的影响,按照标准试验方法测定其立方体强度和弹性模量.在应变控制加载的条件下,得到了包含上升段和下降段的应力-应变全曲线、割线泊松比和体积应变等变化规律,并与普通混凝土试验的结果进行了对比.结果表明,高性能混凝土的轴压性能与普通高强度混凝土类似,骨料对混凝土的强度影响较小,而对变形和弹性模量的影响较大.

| Abstract: | An experimental study of the axial compression behavior of high performance concrete with fly ash and mineral powder has been performed using 100 mm×100 mm×300 mm prism specimens subjected to axial comp-ression.Cubic strength and elasticity modulus are also given through standard test method.Loading through a servo-hydraulic testing machine under the displacement control is used to get the complete stress-strain curve.The main test results including failure modes,curves of stress-strain and stress-volumetric strain are given and discussed.It is found that the aggregate has little effect on the strength and the ratio of passion,but it has a great effect on the elasticity modulus and peak strain. |
