Abstract

It was experimentally founded, that the size and the topology of the particles the active additives in the composition of new kinds of high performance concretes is a very important parameter (as its chemical activity), especially if the combination of this additives possible to realize the nonlinear phenomena. The sample of the combination of high disperse silica fume and nanocarbon particles fulleroid type - Astralenes^®.was researched. It was founded also the possibility of high level of increasing the life-time of polymer components in composite concretes due the presence the fulleroid type nanoparticles.
