再生混凝土大偏压长柱受力性能试验研究

Experimental Study on Mechanical Behavior of Recycled Concrete under Large Eccentric Compression

随着混凝土材料用量不断增加,生态环境遭到破坏,废弃混凝土材料可通过再生骨料混凝土技术进行再次加工。通过施加压力的试验可知再生混凝土长柱破坏机理与普通混凝土柱子的破坏机理一致,但变形量与普通混凝土相比较大,当试验的掺入量增加时,承载能力有一定下降趋势,当掺入量达到40%时,混凝土长柱的承载力与之前相比下降了7.29%。再生混凝土长柱的承载能力可以按照现行的方式进行分析计算。

With the increasing use of concrete, the ecological environment is destroyed, and the waste concrete materials can be reprocessed through the technology of recycled bone cement. Regeneration consistent failure mechanism of concrete long column failure mechanism and ordinary concrete columns through the test results of pressure, but the deformation compared with ordinary concrete, when the test incorporation increases, the bearing capacity is decreased, when the doping amount reaches 40%, the bearing capacity of concrete columns compared with before fell 7.29%. The bearing capacity of recycled concrete long columns can be analyzed.
