In paper results of researches on activation of water-cement suspensions by manufacture of foam concretes nonautoclaving solidification and to increase of activity of cement by machining in electromagnetic apparatuses of a vortex band are presented.

Keywords: machining on cement suspension, increase of durability of a cement stone, processing time of cement, re-crushing of cement, activity of cement, activation, apparatuses of a vortex band

In article the analysis of a condition of production of cement concretes with use nano-technologies is carried out. A production technique of cement concretes with introduction nanoparticles and simultaneous levigating of a cementing agent is offered.

Keywords: nanodispersible modificators, nanotechnology, re-crushing portland cement parts, a strength improvement of cement concretes, vortex band apparatuses, activity of cement, activation, apparatuses of a vortex band
