配比建筑垃圾再生材料大型固结试验分析

Analysis of Compression properties of Recycled Materials for Construction Waste

本文利用室内大型固结试验,分析了建筑垃圾再生材料三种配比、四种压实度在不同荷载条件下的压缩性质,通过研究不同配比材料的应变与荷载的关系、孔隙比与配比的关系、压缩系数与配比的关系、应变与配比的关系及应变与压实度的关系,得出:建筑垃圾再生材料的变形随着荷载的增大而增大,不同的压实度会使各配比的孔隙比的峰值有所不同,砖渣的含量对建筑垃圾再生材料压缩性能有较大影响,在进行现场施工时,应注意控制砖渣含量。

In this paper,the indoor large-scale consolidation test is used to analyze the three kinds of construction waste materials and the compression properties of four compaction degrees under different load conditions.The relationship between strain and load of construction waste materials,the relationship between void ratio and ratio,the relationship between compression coefficient and ratio,the relationship between strain and ratio,and the relationship between strain and compaction degree were analyzed.The results show that the deformation of the construction waste regeneration material increases with the increase of the load,and the different compactness will make the peak ratio of the ratio of the ratios different.The content of brick slag has a great influence on the compression performance of building waste recycled materials.When carrying out onsite construction,attention should be paid to controlling the brick residue content.
