SOLID DISPERSED COMPOSITION OF CALCIUM NITRATE, CONTAINING ANTI-CAKING AGENT Russian patent published in 2019 - IPC C01F11/44 C01F11/36 C01F11/42 C04B14/06 C04B20/00 C04B22/08 C04B28/02 C04B40/00 C04B103/12 C04B111/00 C05C5/04 

FIELD: construction.

SUBSTANCE: invention can be used in construction in making construction mixtures and binder compositions. Solid dispersed composition of calcium nitrate contains particles with average size of 0.1 to 1 mm and contains an anti-caking agent consisting of a solid disperse compound. Said compound contains atoms or ions of silicon and oxygen, including compounds such as silicon dioxide, finely dispersed silicon dioxide or diatomaceous earth. Average particle size of said solid dispersed compound ranges from 0.05 to 750 mcm. Solid dispersion compound is present in amount of 0.01 to 2 wt%. Disclosed is use of solid disperse composition of calcium nitrate as setting accelerator for cementing preliminary mixed binding composition.

EFFECT: invention enables to obtain a solid dispersion composition which does not affect the strength of concrete when it is used.
