abstract

The purpose is to develop composition for surface modification of steel fibers used for steel fiber concrete to strengthen the anchoring fibres in concrete and create it corrosion passivating protective layer.

A new composition of modified anticorrosion compositions is developed for processing of steel fibers. The use of the developed composition allows for steel filament fibers to volume concrete throughout its length by binding the surface with a concrete matrix and to minimize the possibility of unimpeded stretching of the fibers under the action of loads, while still protecting the fibers from corrosion.

Processing of steel fibers modified anticorrosive composition can be used to receive reinforcing steel elements with reinforced anchoring properties. Surface treatment of fiber modified anticorrosion composition can significantly (more than 60 %) increase the tensile strength of dispersion-reinforced concrete, while still protecting the fiber from corrosion, which enables to increase durability dispersion-reinforced concrete
