It is shown that using of compound KBM allowed to
reduce the expense of binder, to increase the solidity of
mixture and its plastic properties. Besides, the complex of
additives included into KBM increased the antiburning-on
properties and resistance to scab-forming of agglutinant
sand.

Hardening of agglutinant sands on lignosulphonate
binding agent is the result of two processes: oxidation-reduction in the system lignosulphonate acids — persulfuric
natrium in the early stages of hardening and hydration of
cement in the latter stages.

There is shown that using of the compound
connecting system allows to carry out not only receiving
of the stable material but to provide equal distribution
along the whole mixture volume of all components,
forming part of a compound, as well.
