再生混凝土单轴受压应力-应变全曲线试验

完成了不同再生粗骨料取代率下再生混凝土的单轴受压应力-应变全曲线试验,分析了再生粗骨料取代率对再生混凝土的应力-应变全曲线形状、弹性模量、峰值及极限应变的影响.研究表明：再生混凝土的应力-应变全曲线的总体形状与普通混凝土的相似,但曲线上各特征点对应的应力和应变值不同;再生混凝土的弹性模量明显低于普通混凝土的;再生混凝土的峰值应变与峰值应力大于普通混凝土的.

Experimental Investigation on Complete Stress-strain Curve of Recycled Concrete Under Uniaxial Loading

In this paper the complete stress-strain curves of recycled aggregate concrete with different recycled coarse aggregate replacement percentages are carried out,and the influences of varying recycled coarse aggregate contents on the complete stress-strain curve,peak stress,peak strain and elastic modulus are analyzed.The results show that the stress-strain curves of recycled aggregate concrete are similar to those of the conventional concrete,however,in terms of the recycled aggregate concrete,the peak strai...
