FIELD: defectoscopy.
SUBSTANCE: invention relates to investigation of strength properties of concrete and can be used to control strength of concrete structures. Concrete strength is determined from the dipping depth of the dowel-nail into the tested concrete from the construction-and-mounting gun. On the dowel-nail cylindrical surface a scale is applied with the division price corresponding to strength of the known concrete types.
EFFECT: high information value when determining strength of concrete and reduced time (labor costs) for determining strength of concrete.
