Effectiveness of fire protection of wood with an organic-mineral coating with the addition of aluminum hydroxide Open
Today, there are two methods of fire protection for wood. The first is impregnation with flame retardants, most often based on inorganic salts. When wood is moistened, fire retardants dissolve in a humid environment and gradually wash out …

Study of the effect of organic shell on the leaching of protective compositions from wood protected from fire Open
Today, there are various ways to fireproof wood. When wood is moistened, flame-retardants dissolve in a humid environment and gradually wash out to the surface, after which the fire protection effect decreases over time. Acid-based product…

Radiation protective properties of fine-grained concretes and their radiation resistance Open
Studies have shown that the thickness of the half layer of the gamma radiation flux attenuation with E = 662 keV is 3,5-5,2 cm (depending on the concrete density average) and for a neutron flux with E = 2,5 MeV is 5-6 cm. The radiation res…
