ABRASION RESISTANCE OF CONCRETE AND THE USE OF

The current study shows that aggregate hardness plays a dominant role, and comparisons of concrete materials can be contrived such that the rule of thumb does not apply. The abrasion resistance of high strength concrete depends strongly on the hardness and abrasion resistance of the mineral used for coarse aggregate.
