Determination of Concrete Strength by Nondestructive Methods

Abstract

This paper considers problems of improving the non-destructive control of concrete strength from the standpoint of: selecting the most economic methods; determining the required number of individual tests at a location to obtain an average in-place test result with the same degree of confidence by various methods; and modifying the acceptance criteria of ACI 318 to reduce the consumer's risk without changing the producer's risk. The ways of reducing labor consumption of nondestructive tests are recommended.
