无机聚合物混凝土应力-应变全曲线试验研究

Experimental study on stress-strain curves of inorganic polymer concrete

通过对无机聚合物混凝土材料进行基本力学性能试验,就其弹性模量、泊松比及应力-应变全曲线进行了试验研究与探讨。试验结果表明:IPC40相比于相同强度等级的普通混凝土的弹性模量小11.8%,泊松比大22.2%,轴压试验的峰值应变值也高于普通混凝土。试验得到的应力-应变全曲线与采用的分段式模型吻合较好,为无机聚合物混凝土的力学性能研究提供参考。

Basic on mechanical properties experiment of inorganic polymer concrete （1PC）, studied and discussed its elastic modulus, Poisson＇s ratio and stress-strain curve.It is shown by the test results that the elastic modulus of IPC40 if 11.8% lower and the Poisson＇s ratio is 22.2% higher than the same level ordinary concrete, the peak strain values of the axial compression experiments is also higher than that of ordinary concrete.Moreover, the stress-strain curve according to the experiment match well with segmented model, it can provide a ref-erence for the research on mechanical properties of inorganic polymer concrete.
