摘要
通过轻骨料混凝土LC30,LC40与普通混凝土C30,C40的对比试验,研究了同等强度等级下轻骨料混凝土与普通混凝土的力学性能;得出了不同强度等级的轻骨料混凝土的应力应变关系曲线.将试验结果与规程模型进行对比,分析其差异,进一步给出下降段的应力应变曲线方程.
According to the contrast test of lightweight aggregate concretes LC30,LC40 and concrete C30,C40,the mechanical property of lightweight aggregate concrete and ordinary concrete under the equality strength grade were obtained,together with the regularity of the stress-strain curve of lightweight aggregate concrete under the different strength grade.Moreover,equation of the down part of stress-strain curves was given by analyzing and comparing the results from the planning model with the experimental data.
