Abstract:
The objective of the research described in this article was to produce a simple test causing little disruption to provide direct information on the strength of high alumina cement concrete in prestressed concrete X-shaped beams produced under factory controlled conditions. A pullout test which is based on the correlation between compressive strength of concrete and the forces in a wedge anchor needed to produce internal cracking in concrete was developed. The test method and research leading to its applica-tion are described.
