钢纤维膨胀混凝土轴压应力应变全曲线研究

Study on Axial Compression StressStrain Full Curvesof Steel Fiber Reinforced Expansive Concrete

钢纤维膨胀混凝土是将钢纤维乱向分散于膨胀混凝土中 ,形成的一种集承重与防渗为一体的新型建筑材料 .采用一组合弹簧作刚性辅助架的方法 ,成功地测出了钢纤维膨胀混凝土轴压应力～应变全过程曲线 ,在试验研究基础上 ,对其应力应变全曲线进行了数值模拟 ,给出了与试验结果符合较好的模拟方程 .

Steel fiber reinforced expansive concrete is a new building material made by putting steel-fibers into the expansion concrete,and has good mechanical performance and permeability resistance The uniaxial compression stress～strain full curves for steel fiber reinforced expansive concrete are measured successfully by a united spring system Based on the test results, numerical simulation for the stress～strain full curve has been carried out The simulation equations are given,which show good agreement with the experimental results
