Describe resistance to abrasion and skidding as it relates to aggregates.
What will be an ideal response?
Abrasion resistance is important when the aggregate is to be used in an area that is subject to heavy abrasive use, such as a factory floor. Aggregate for abrasion resistance is tested following ASTM C131 standards. To give skid resistance, the siliceous particle content of the fine aggregate should be 25 percent or more.
