Abstract To effectively improve the poor engineering properties of loess and
enhance its seismic performance, the industrial by-product lignin is used as a
modified material. Based on lots of dynamic triaxial tests, the dynamic elastic
modulus and damping ratio of lignin-modified loess were tested. The effects of
lignin content on the dynamic elastic modulus and damping ratio of lignin-modified loess were analyzed. Combined with scanning electron microscopy (SEM)
and X-ray diffraction (XRD), the microscopic mechanism of lignin to improve
the dynamic properties of loess was studied. The results show that lignin can
effectively modify the dynamic… More >
