Nanoadditives in the form of high-effective sol-additives of different nature are considered. It was determined that SiO2nH2O and Fe(OH)3 additives raise cement hydration activity, compressive resistance and tensile strength as well as crack resistance factor. When using colloid solutions, forming structure density rises, that allows obtaining high-strength concrete made from ordinary cement. When ferrous hydroxide is presenting, corrosion resistance of reinforcement increases.
