ABSTRACT:
The present invention relates to a method for verifying concrete flexural strength by establishing a predictive correlation between concrete flexural strength and a second strength parameter, such as direct tension or indirect tension, measuring the value of that second strength parameter for a batch of concrete, and estimating the flexural strength of the batch by way of the second strength value and the correlation.
