The purpose - is to develop Recommendations on the use of non-metal composite grates in the repair of transport structures by the method of gunning, and the Album of corresponding technical decisions Methods of research - were used theoretical and experimental methods of research for DBN V.2.3-6: 2016, DBN V.2.3-14: 2006, DBN V.2.3-22: 2009, DSTU-N B-B2.2-1-1.65: 2012 , СОУ 42.1-37641918-112: 2014, GOST 32487: 2013. Experimental laboratory concrete samples reinforced with composite gratings were made by the method of gun fire. Physico-mechanical and physico-chemical tests of composite and concrete samples are performed. The results of the work -Moveled experimental studies have shown that composite materials have high tensile strength, compression and cut, corrosion resistance, good adhesion to concrete and the thermal expansion coefficient close to it. It has been shown that composite materials - reinforcement and gratings are very promising during the fireproofing, they increase the physical and mechanical properties and durability of trashchetbetonnyh layers and shells. As a result of the tests of physical and mechanical properties of laboratory concrete samples made by the method of gunning, it was established that the strength of concrete beams and plates, reinforced with a mesh of composite reinforcement is one third higher, and the deflection is twice less than the values ??of similar specimens, reinforced with a grid of steel fittings (from equal in diameter of the rods and cellar lattices). The Recommendations and the Album of technical decisions on the use of non-metal composite grates in the repair of transport constructions by the method of gunning are developed, agreed and approved in the established manner. Application: during repair of reinforced concrete constructions and structures by a method of gunning.
