FIELD: the invention is used for definition of durability of heavy concretes in constructions.
SUBSTANCE: the essence is in that measuring of the speed of ultrasound vibrations in the controlled sections of a construction is executed, manufacturing of reference sample out of high-test concrete, definition of meanings of durability of concrete and the speed of the ultrasound vibrations in reference samples, registration of changing of the speed of the ultrasound vibrations at different intensity of the ultrasound vibrations introduced into reference samples, building dependence of durability of reference samples on pressure from changing the speed of the ultrasound vibrations in samples, definition of meaning of maximal durability of concrete in reference samples by way of extrapolation of received dependence of durability of reference samples on pressure from changing the speed of the ultrasound vibrations in samples to zero meaning of changing of the speed of the ultrasound vibrations in samples and the following estimated definition of durability of the concrete on pressure in the controlled sections of the construction. Besides average humidity of the concrete in reference samples and in the controlled sections of the construction, and durability of concrete is estimated of empirical expression connecting the average speed of propagation of the ultrasound in the controlled section of the construction and also average humidity of the concrete in the controlled section of the construction with durability of the concrete.
EFFECT: increases accuracy and reliability of definition of durability of heavy concretes.
