It deals with conditions of regulation of morphologic and disperse composition, energy state of individual crystals of portlandite which are obtained in accordance with lump-lime hydration nanotechnology. The study presents the grounds for modes of contact condensation structure formation of clinkerless composites with portlandite stone matrix.
