Question

Difference between abrasion and attrition of aggregates

Answer 1

ABRASION:

Abrasion of aggregate is rock erosion occurring when rocks at high velocity rub against each other and friction effect causes surface grinding.

ATTRITION:

Attrition also occurs on rocks, however, its undue grinding as a result of weight of heavy rock grinding another rock this can be due to gravity.

Aggregates are loosely held materials on a certain surface. These materials are usually eroded away from rocks when acted upon by agents of erosion.
