| Title of the article | Research of influence of an additive of KDU-1 modified by carbon nanotubes, on physicomechanical characteristics of high-strength fiberconcrete |
| Abstract. | This work is dedicated to the analysis of influence of an additive of KDU-1 modified by carbon nanotubes, quantity and fiber type on the physicomechanical properties of concrete, steel-fiber-concrete, glass-fiberconcrete and steel-glass-fiberconcrete. To ensure closest relation of test results to real conditions, Kazmetrostroy concrete goods plant management and laboratory staff worked in a close correlation. The ingredients used in a concrete mixture were identical to those used for production of ferroconcrete blocks of distillation tunnels of the Kazan subway. To determine deformative properties of fiberconcrete standard samples were made. Graphs of change of durability of concrete on compression and a bend were drawn on the basis of test results. Given research proves that two-level reinforcement of a matrix by a glass and steel fiber allows longer time operability of concrete at increased bending force and increases crack resistance. Applying developed additive (KDU-1 modified by carbon nanotubes) makes possible reduction of a cement consumption from 490 kg/m3 to 355 kg/m3. |
