.... In this study, a variety of prevention measures that claim to prevent corrosion of steel were examined. Specifically, barrier coating, i.e., polymer, epoxy coating, as well as the sacrificial coating, i.e., hot-dip galvanising, methods were tested. Testing specimens were made by inserting loading pins between...

... conducted on discontinuities in shale and sandstones. These were partly weathered and sometimes coated by coal. Friction angles range from 10° for coal-coated joints in sandstone to 40° clean joints in sandstone. The discontinuities were scanned with a 3D laser scanner for estimating the surface roughness...
