In the aggregates industry, these rocks are classified as crushed stone, sand, gravel and slag. We use aggregates every day. Streets, bridges, roads and sidewalks are made of concrete or asphalt which is mostly made up of aggregates combined with a binder that acts like glue. Concrete is used in foundations and basements for houses.
QUIKRETE® Concrete Bonding Adhesive can be used for interior applications and exterior applications over 1" thick. Do not use Concrete Bonding Adhesive in continuously wet environments. Concrete Bonding Adhesive is painted on the surface of the old concrete and allowed to dry before new concrete or QUIKRETE® Sand Mix is applied.
