In this study, the influence that crushing and moisture exerted on mechanical properties of crushed stone was evaluated, and the method for evaluating mechanical properties of crushed stone in high strength concrete with its raw ore was examined. The results indicate that mechanical properties of crushed stone are appreciable as those of its raw ore because serious crack in crushed stone for high strength concrete is not caused at the stage of crushing. However, when compressive strength of crushed stone with large percentage of absorption is evaluated, it is necessary to consider the influence by the difference of total moisture content between crushed stone in concrete and its raw ore.
