Modification of Dasaltfiberconcrete by Nanodispersed System

Management of cement systems structure formation can be achieved by introducing nano-dispersed components, which is supported by studies of various scientists. However, the effect of their use in basaltfiberconcrete to date has not been studied. The article presents the results of research modification basaltfiberconcrete various nano- and ultradisperse carbon-based additives. According to the research found that by the introduction of multi-walled carbon nanotube dispersion is possible to differentiate the composition of the electoral of tumors on the surface of basalt fibers, providing increased adhesion in the boundary layers of the system, contributing to a significant increase in strength characteristics of modified basaltfiberconcrete samples. A modification at basaltfiberconcrete by soot dispersion is formed partially crystallized calcium hydrosilicate tobermorit structure, also sealing the contact zone of reinforcing fibers and a cement matrix. Based on the results of the research we can talk about structural modification of basaltfiberconcrete by nano- and ultradisperse carbon-containing systems, intensifying the process of hydration of Portland cement matrix and the seal on the border with the surface of basalt fiber.
