Crushed Concrete Aggregates - Properties and …
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

GRADE OF CONCRETE And their type of Grade - …
GRADE OF CONCRETE. Concrete of Grade is a mixture of Portland cement, water, and coarse and fine aggregates. It consolidates into a hard mas because of a stone reaction called hydration between cement and water. Proportioning a concrete mix for a given purpose is thus the art of obtaining a suitable ratio of the various ingredients of concrete with the required properties at the lowest cost.
