STUDY OF VOLUME CHANGES OF PLASTER WITH MINERAL ADDITIVES

Pre-treatment viznachaє infusion of mineral additives on the natural deformation of gypsum virob. The main reason for the low water resistance of the gypsum viruses is stated. The reason is є a wedge vise. Such a grip breaks out local contacts with crystals. Tsi cause one to dress up in a negative synergistic effect. A wide circle of naukovts is looked around. Fakhivtsi detect the inflow of mineral and chemical additives on the water resistance of the gypsum. Zokrem is honored that the power of materials on the basis of inorganic viscous accumulation of the manifestation of electrostatic interconnection of subordinate electric spheres of structural elements. Before it was confirmed, the value of the biological deformation of the gypsum should be deposited instead of a mineral supplement. Uwagu zoseredzheno on slag blast-furnace granulated chalk.The meta of the statistic was the determination of the degree of determination of the indicator of the uniform lineal deformation of the water saturation (swelling) ew at m / m. Such an indicator can be used with a supplementary indicator of water resistance. In the experimental preliminaries, we used G-10 grade G-10 industrial gypsum, Zaporizhstal blast-furnace granulation slag, and a plasticizing additive - sodium lignosulfonate in a 2% mixture of gipsuFor further development, the skin with three eyes was placed vertically near the vessel. A steel overlay was placed on top of the zrazok. Before the overlay, an indicator of the year-old type was set, fastened to a laboratory stand. The distance was fixed to the cob to show the indicator. The deformation took 3–5 years to develop. In the meantime, having reached the maximum value and mayzhe, the odra was repaired to decrease. At the same time, there will be a projection of the addition of a supplementary indicator of water resistance to the water consumDue to the increase in the amount of slag, the deformation will decrease. The price decrease did not demonstrate a linear character. The character is sickly. This deposit is analogous to that of the deposits of the mines and water from the slag. Minimal deformation is more favorable for a piece gypsum stone with a removable slag W / (H + W) 0.05–0.1 and ponad 0.27. Tse pіdtverzhu podpuschennya about injections at low water resistance gіpsu ozklinuvalnogo inlet water. The wedge-shaped inflow of water is drawn through the contacts between the crystals and particles in the structures of the hypers. The values of the natural deformations of a piece gypsum stone are projected according to the parameters of the water resistance.
