FIELD: technological processes.
SUBSTANCE: invention relates to the field of silicate materials technology. Proposed is containing calcium silicate hydrate (CSH) in the form of defective tobermorite nucleating agents containing suspension obtaining method. Method comprises reacting of the Ca containing compound at least one source, with the Si containing compound at least one source, in the aqueous medium and in the presence of a dopant, selected from the group consisting of the P containing compound, the B containing compound, and mixtures thereof. Reaction is carried out at a temperature of from 100 to 350 °C and endogenous pressure or pressure maintained constant in the range from 0.1 MPa to 50 MPa.
EFFECT: invention ensures obtaining additives that are effective as the concretes or cement based material reinforcement accelerator.
