Sep 22, 2017· A concrete compressive strength test machine works by progressively applying force on a specimen. Because strength is defined as the maximum load carried divided by the average crosssection area, the most logical way to determine the strength of a specimen is to load it until it fails.

Mar 30, 2012· When the load on the pullout shaft is increased to failure, a conical piece of concrete will be taken out. The pullout strength can be related to compressive strength to determine whether posttensioning may proceed, forms and shores may be removed, or winter protection and curing may be terminated. Postinstalled anchors also can be used.
