STRUCTURAL ELEMENT AND METHOD OF REINFORCING BUILDING STRUCTURE Russian patent published in 2011 - IPC C04B28/02 C04B16/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a structural element and a method of reinforcing a building structure. The reinforcing structure is made from poly[benz(1,2-D:5,4-D')bisoxazole-2,6-diiyl-1,4-phenylene] fibre and is incorporated into a layer of mortar. The mortar contains the following in %: cement 5-95; finely ground inert mineral filler 10-70; characterised by particle size smaller than 700 micrometres; chemical additives which include unsaturated copolymer resins 0.1-25; liquefying additives 0.05-2.5; thixotropic agents which relate to the cellulose class 0.005-1. All percentage content values are weight percentages and are obtained based on total weight of the mortar. The method involves formation of a layer of mortar on a reinforced structural element and incorporation of the reinforcing structure into the layer of mortar.

EFFECT: ensuring thermohydrometric transfer between the building structure and the external medium, where the structural element demonstrates fire resistance and resistance to aggressive chemical media, as well as good mechanical properties.
