Aggregates for Concrete PCA

No correlation between aggregate abrasion and concrete abrasion. Siliceous content 25% for good skid resistance. The abrasion resistance of an aggregate is often used as a general index of its quality. Abrasion resistance is essential when the aggregate is to be used in concrete subject to abrasion, as in heavy-duty floors or pavements.
