Typically, a threaded rod or rebar which is installed in a predrilled hole in a base material with a two part chemical compound.

A material other than water, aggregate, or hydraulic cement used as an ingredient of concrete and added to concrete before or during its mixing to modify its properties.

Concrete that has been mixed with air-entraining additives to protect against freeze-thaw damage and provide additional workability.

The maximum design load that can be applied to an anchor. Allowable loads for mechanical and adhesive anchors are based on applying a factor of safety to the average ultimate load.

A design method in which an anchor is selected such that service loads do not exceed the anchor’s allowable load. The allowable load is the average ultimate load divided by a factor of safety.

Reactive ingredient used as a setting agent for epoxy resins to form highly crosslinked polymers.
