Efficient Dry Mixes for Repair and Restoration Works
On the basis of literature data and accumulated experience, the classification of dry building mixes for repair and restoration works is offered. In the course of development of repair andrestoration compositions with preset operational properties main propositions of geonik and the law affinity structures formulated within the frame of this scientific direction are used.The law affinity structures is based on cause-and-effect relations, their interaction which determine properties of the common system as a whole. Dry repair heat-protective solutionshave been developed with due regard for the law affinity structures. Expanded perlite sand is used as a filler. Complex organic-mineral modifier which makes it possible to control theprocesses of structure formation in the course of repair mixes hardening and add increased chemical activity to the system has been obtained. Repair compositions on the basis of rawmaterial recourses of the Kursk Magnetic Anomaly and the developed complex organic-mineral modifier are offered. Microphotographies of contactzones of repair compositions on variousbases are presented Results of the electronic microscopic studies are fully confirmed by results of physical-mechanical tests which testify high density and strength of contacts ofrepair compositions with the base.
