Influence of propeller material hardness, testing time, rock properties, and conditioning on LCPC rock abrasiveness test

LCPC rock abrasiveness test is gaining popularity for quick estimation of rock and soil abrasiveness in the preliminary site exploration stage of tunneling projects. However, there are parameters such as test propeller hardness and testing time, which may affect the test results thereby influencing the tool wear rate estimates of the tunneling machines employed in those projects. This study evaluates LCPC rock abrasiveness test by using both the...
