The review of methods for manufacturing nano-concretes in the nowadays building industry is presented. The first method is a finish grinding of traditional Portland cements until nanosize values and producing nano-cements. The technology of producing this nano-cement is based on the combination of mechanical-chemical activation of Portland cement grains in the presence of modifiers with the grinding of materials until the nano-size state. The second method is introducing nano-particles in Portland cement. Micro-silica is produced as a byproduct in the course of producing the elemental silicon and silicon-containing alloys and provides the creation of super-strong and durable concretes. Introduction of the carbon nanotube dispersion accelerates the hydration process, regulates the porous structure of nano-concrete. The presence of nano-particles suitable for modification of concretes is detected in some natural minerals and industrial waste. The third method is the synthesis of nano-particles directly in concrete mixes with the use of initial substances – precursors. Nano-particles of the silicon dioxide obtained by the so-called sol-gel technology show high efficiency
