Several ageing tests of CGN-based grout were carried out by LI et al [22], and the results reveal that the material has high... and rainless, and occasional extreme rainfall climate. Concentrated rainfall and intensive evaporation lead to the deterioration of earthen sites [30]. Besides, soil mass above subgrade is also affected......

biocompatibility of titanium, the problem of implant rejection has to be completely solved. In addition, titanium is known to have poor wear performance [7] because of its high friction coefficient. As biocompatibility and wear resistance are properties related to the surface of a material, a number of surface modifications have been proposed for titanium alloys [8]. BALLA et al [9] found that laser surface......
