The strength characteristics of the host are determined on sample beams from a mixture of Volsky's mixture in the ground and sand (1: 3).

The mixing of the mixture is carried out with a soda – water solution of soda ash of varying density. After hardening for 28 days in nostril conditions, some of the samples are tested for strength and deformation, the other part is subjected to testing after keeping at 50 and for 3-D hours, after which they are also subjected to testing} III strength and deformations.

The compositions in the properties and properties are given in table. 2

Offered in a tent with an expansion effect in the range of O, 50-0.60 mm / m and preserving the prg14 during operation at 50 ° C, can be used in industrial materials and other areas as a material for repair work in thermal units with working temperature up to 110 (.

In the proposed one, the ratifying element is an open-casting or converter pitch synthesized in the process of hydration and hardening, containing a mineral (I lF, gel and iron hydroxide (Fe, 0., ()), Leading to the development of internal stresses in the stone In general, it (pT determines the increase in the volume of its solid phase.

ZI, 0.

The absence of loss of strength under operating conditions at 50–110 ° C of the proposed binder, as compared to the known, is due to the high content of calcium aluminates in the form of the CA mineral and the presence of trace elements — niobium oxides in the operm of ferroniobi production. When calcium aluminates are dissolved in an alkaline medium, ions are formed in the form of A1 (OH) complexes, which, taking part in the hydrolysis reaction, increase the pH of the liquid phase, which is the cause of strength in the gum. The presence of trace elements in the form of niobium oxides in the structure of the phases formed during hydration into a binder promotes an increase in the performance properties of the binder at the temperatures considered. In this case, the scheme of the occurring processes can be represented as follows.
