A significant problem in the construction area in the Russian Federation is a ban on high-rise wooden buildings. To solve this problem, it is necessary to study the state of the issue in the world and in the Russian Federation, and analyze the development prospects of this area. The necessity to optimize the existing methods for testing wooden building structures is shown. Examples of various documents regulating the production and use of wooden and composite building structures are given. The work reflects in detail the international experience in the implementation of the main provisions of regulatory documents and European tests for fire resistance, which shows the possibility of implementing such an experience in the Russian Federation. To develop a regulatory framework for wood structures in high-rise construction, it is necessary to conduct large-scale experiments on wooden structures to study their fire resistance. In this case, it is necessary to take into account the features of combustible building materials.

“…Here, the investigator must understand the response surface much better, by approximating it with polynomials of the second and sometimes even third degree. Frequently the experimenter faces screening experiments, which aim to emphasize the influence of a multitude of possible effects [ 1 , 2 , 3 , 4 , 5 ].…”

“…In addition, flame retardants must not only provide the required fire protection for the protected structure under external flame impingement, but also ensure good adhesion to the substrate material or structure, the required durability under normal operating conditions, manufacturability, and application to the protected structure [ 41 , 42 , 43 ].…”

“…The main types of binders used in fire protection intumescent coatings are PVAD (polyvinyl acetate dispersion), liquid glass, acrylic dispersion, acrylic resins, acrylic copolymers, rubber, epoxy, perchlorovinyl, and silicone resins. Numerous standard studies are described in the literature, where the influence of the nature of the binder and its work at a certain ratio of antipyrenes on the final properties of the coating is considered [1][2][3][4][5][6].…”

“…Ammonium polyphosphate is an inorganic polymer of a branched structure-ammonium salt of polyphosphoric acid, fine white powder, incombustible, non-toxic, and poorly soluble in water. When heating PFA to temperatures of about 250-280 • C (depending on the degree of polymerization), endothermic decomposition with formation of polyphosphoric acid and release of ammonia occurs [7][8][9][10].…”

Fire Protection of Building Constructions with the Use of Fire-Retardant Intumescent Compositions

The influence of basic components of intumescent paint on fire protection properties is studied. The resulting changes in properties are assessed by the intumescence coefficient and thermal analysis data. Influence of the binder polymer composition on fire protection properties under the same conditions was evaluated, quantitatively using the example of fire-retardant water-dispersion paint; the best result was obtained in the formulation based on vinyl acetate copolymers. The brands of ammonium polyphosphate (PFA) from different manufacturers were investigated under the same conditions. The results of the thermal analysis and testing of the physicochemical properties of the samples on various PFAs are presented, with conclusions about their influence on the fire-retardant properties of the paint. The results of the thermal analysis of the influence of orthophosphoric acid, as a modifying additive, on the fire-retardant properties of the paint are presented.
