ExtEndEd AbstrAct: To popularize scientific achievements the main results of Russian and foreign scientists' research are published in the form of abstract. The research «Increasing of concrete strength with carbon nanotubes by means of hydrodynamic cavitation» contains the calculation of prime cost of the main raw components which are necessary to produce fine-grained concrete with strength class B55, that demonstrates the economic efficiency of application of CNT as modifying additive for

Modification of concrete matrix with CNT leads to higher breaking point of compressive strength and that makes it possible to reduce discharge intensity of cement by the strength unit of the material. In this case introduction of 0,05% initial CNT of binder mass into concrete led to 1,5 times increased strength-to-weight ratio. The amount of saved resources was determined as the cost difference between amount of raw materials which are necessary to produce concrete B55 class of traditional composition and the concrete similar by the class obtained due to introduction of carbon nanomodifier into it. The choice of the cost of 1 gram of multilayer CNT was based on the analysis of commercial offers of Russian and foreign companies that are specilized in manufacture and realization of carbon nanomaterials.
