FIELD: studying the properties of concrete.
SUBSTANCE: method for determining the strength of concrete is proposed, which includes passing a direct electric current during its manufacture until the end of setting, loading the sample and determining the strength according to the dependence of the electrical characteristic - load, characterized in that the maximum value of the current strength and the time it takes to reach it are determined, and the concrete strength value is evaluated by a pre-established dependence of the maximum current value and the time to reach it on the strength of the concrete.
EFFECT: improved accuracy of the results of non-destructive testing in determining the strength of concrete.
