摘要
从抗压强度、本构关系、弹性模量三个方面对再生大骨料自密实堆石混凝土和天然大骨料自密实堆石混凝土进行了对比研究。结果表明再生大骨料自密实堆石混凝土和天然大骨料自密实堆石混凝土二者抗压强度相近,本构关系相似、弹性模量相差不大,再生大骨料自密实堆石混凝土在一定程度上可以替代天然大骨料自密实堆石混凝土。
The compressive strength,constitutive relations and the elastic modulus of big recycled aggregates fill concrete and big natural aggregates fill concrete were studied comparatively.The results showed that two kinds of self-compacting concrete had almost equal compressive strength,similar constitutive relations and the elastic modulus.So,the big recycled aggregates could substitute the natural aggregates in a certain extent.
