Crushed Concrete Aggregates - Properties and Uses of Recycled .

Shear strength of recycled aggregate concrete is lesser than of normal concrete. This is because the recycled aggregate from field-demolished concrete for example can be relatively weaker than a typical natural aggregate. In general there is a 10% decrease in strength when recycled coarse aggregates are used. Uses of Crushed Concrete Aggregates
