fiberreinforcement

It is shown that one of the innovative ways of obtaining of Rapid-hardening concretes with enhanced performance for fortifications is the use of nanotechnology techniques related to the directed process of structure formation by modifying of nanoscale elements. The problem of improving of the higher-speed impact stability of high-strength concrete by hybrid reinforcement of their structures at the micro level – by energy-active ultrafine mineral additives and macro level – by dispersed fibers is considered.
