The researches directed on control by gelation, regulating of composition and properties of swelling up fireproof composite coatings (fireproof composites) for security of fire-resistant building constructions are presented. In-process on the basis of the topological analysis and gelation modelling component composition schungite in fireproof aggregates with demanded thermal and hardness in performances is optimised. The interconnection of structural performances, modifications of mineralno-phase composition and properties of fireproof aggregates is experimentally positioned at high-temperature impact. The rated-analytical method positions efficiency of fireproof aggregates for raise of flame-resistance of reinforced concrete constructions. The obtained data have allowed to develop representations about the gelation gear at interacting of corpuscles schungite in swelling up cement system at high-temperature heat and justify to approach to creation of effective fireproof aggregates for fire-resistant building constructions.
