FIELD: concrete materials.
SUBSTANCE: invention is related to a method for determining or continuously monitoring the degree of hardening (strength gain) of concrete materials, products and structures. The method can be used to optimize the construction process by creating feedback to reduce time costs. The method for determining the degree of hardening of a concrete product includes the following stages: during the process of gaining strength or at the end of the strength gain of the specified product, into which a test material is previously introduced, which is an electrically conductive or semiconducting additive or a composition containing at least an electrically conductive or semiconductive additive and a concrete mixture, measurement of changes in the electromagnetic properties of the specified test material as part of the specified product are carried out; the degree of hardening of the specified product is determined based on a comparison of the measured electromagnetic properties of the test material in the composition of the specified product and reference data on the dependence of the electromagnetic properties of the specified test material on the degree of hardening of the concrete mixture of the specified product.
EFFECT: invention is a method for monitoring the degree of hardening, which, depending on the formulation of the problem, can be carried out as quantitative, non-destructive, continuous, for monitoring hardening in real time directly on the structure at one point or several points simultaneously.
