The article provides literature data on the use of steel fiber reinforced concrete. The results of the development of fiber-reinforced concrete compositions modified with a nano-additive are presented. The dependence of the strength characteristics of fine-grained concrete on the amount of carbon nanotubes introduced has been determined. Studies of the stability of a suspension of mixing water with the inclusion of carbon nanotubes obtained using ultrasonic dispersion technology with the UZG13-01/22 device have been carried out. The optimal time for using activated sealing water has been set, which is 100 min from the moment of preparation. As a result of the conducted research, the composition of concrete was selected with the integrated use of Mixarm steel fiber with a diameter of 1 mm and a length of up to 54 mm and Taunit-M carbon nanotubes. According to the data obtained, the combined use of these additives with the Polyplast SP-3 superplasticizer makes it possible to increase compressive and flexural strength by 30%. In addition, an improvement in the intensity of concrete strength gain in the early stages of hardening has been determined.

摘要

The article provides literature data on the use of steel fiber reinforced concrete. The results of the development of fiber-reinforced concrete compositions modified with a nano-additive are presented. The dependence of the strength characteristics of fine-grained concrete on the amount of carbon nanotubes introduced has been determined. Studies of the stability of a suspension of mixing water with the inclusion of carbon nanotubes obtained using ultrasonic dispersion technology with the UZG13-01/22 device have been carried out. The optimal time for using activated sealing water has been set, which is 100 min from the moment of preparation. As a result of the conducted research, the composition of concrete was selected with the integrated use of Mixarm steel fiber with a diameter of 1 mm and a length of up to 54 mm and Taunit-M carbon nanotubes. According to the data obtained, the combined use of these additives with the Polyplast SP-3 superplasticizer makes it possible to increase compressive and flexural strength by 30%. In addition, an improvement in the intensity of concrete strength gain in the early stages of hardening has been determined.
