Abstract: In order to study the damage evolution characteristics of freeze–thaw mortar materials under impact load, this paper uses cement silica powder mortar to prepare cylindrical samples, and performs freeze–thaw cycle tests on ...

Abstract: To evaluate influence of blast vibrations on the long-term mechanical deterioration and damage anisotropy of fresh concrete, blast vibration tests were conducted by preparing concrete test blocks at different curing ages. ...

Abstract: In situ stress is a significant characteristic of underground rock masses. This work extended the time-domain recursive method (TDRM) to study oblique wave attenuation across an in situ stressed joint wherein the normal ...
