Abstract In order to study the modification effect of recycled sand on cement reinforced waste slurry (CWS), triaxial test,
scanning electron microscope test and X-ray diffraction test were carried out. The mechanical test of recycled
sand and cement reinforced waste slurry (RCWS) shows that the deviatoric stress–strain curve of RCWS samples
changes from hardening type to softening type with the increase of recycled sand content; the peak stress
increases with the increase of recycled sand content; recycled sand can enhance the shear strength of CWS by
increasing both cohesion and internal friction angle. The microscopic test shows that recycled sand can… More >
