DEVICES FOR MEASURING INTERNAL STRAINS IN HARDENED CONCRETE,
Abstract
The results obtained with two McCarthy type electric-resistance strain gages embedded in concrete are described. A study of the technical literature dealing with embeddable devices shows that the following four types are worthy of further investigation: the Carlson miniature elastic-wire strain meter, the Baldwin brass-foil-envelope (Valore type) electric-resistance strain gage, the Tokyo plastic encapsulated electric-resistance strain gage, and the Deakin Phillips (Potocki type) electro-acoustic strain gage. A laboratory testing program to investigate the comparative performance of the four devices is proposed. (Author)
