Modification of the Fine - Aggregate Concrete by High Disperse Silica Fume and Carbon Nanoparticles Containing Modifiers

Abstract

This work concern the research of the concentration dependences of the influence the micro amounts of the fine disperse silica fume and the carbon nanoparticles containing modifiers on the mobility of the fine-aggregate concrete mixtures and on the pressure strength of concrete. It was founded the high nonlinear dependences of increasing this parameters in the region of the concentration 10-3 – 10-6 % of the mass of concrete. This results provide the possibility to approach the industry application for the high performance concretes technology at the nearest time.
