Abstract:

Although modern concrete construction has developed during the past 60 years, one aspect has remained essentially unchanged�the use of molded cylinders tested in compression to estimate the strength of concrete in a structure. Recently, however, the testing of concrete in place has become more widespread. Methods are of five types: rebound, maturity, pulse velocity, penetration and resistance to pull-out. Each correlates some test result to concrete compressive strength. The article contains descriptions of test methods and case histories.
