STEEL-GLUED WITHOUT ANCHOR JOINT SHORT-TERM STRENGTH EXPERIMENTAL RESERCH ON ACRYLIC MODIFIED COMPOSITIONS

Abstract

The central issue of the paper is the short-term adhesive strength dependence determining from the number of various technological factors and advanced acrylic composition selection for further elements constructions and without anchor joint adhesive development. The results of the experiments on determination the technological equipment without anchor joint strength, in the case of gluing steel plates to the concrete surface with modified acrylic adhesives, are conducted. Short-term strength of adhesive steel-concrete joints testing methods, as well as the determination of the main technological factors influence on the strength of without anchor joint on acrylic modified compositions, are described in detail. The experimental research on the concrete class, adhesive layer thickness and other structural fixing joint characteristics influence on the strength of adhesion are conducted. On the basis of research results, it was demonstrated that regardless from the type of the loading, the adhesive compound geometric characteristics, concrete physic and mechanical properties, the destruction of concrete-steel joint was occurred on the concrete surface. The obtained results of experimental research data can be used for attachment joints projecting and industrial technological lines development, as well as for further polymeric adhesive materials, widely applied in industrial and civil engineering, improvement.
