USING OF THE MODERN EPOXY COMPOUNDS UNDER RECONSTRUCTION OF BUILDINGS AND STRUCTURES

Abstract

The article deals with the question of modern epoxy compounds, which are used under reconstruction building and structures.

The problem of strengthening and renewal of the functional performance of building structures consists in the solution of such a task as the increasing of bearing capacity of structures. The given task is closely related to both change of functionality of a building, and the increasing of loading on its separate structural elements. One of the principal ways of structure strengthening is the building-up of its cross-section. Such a strengthening, which is performed by gluing steel or composite polymeric fiber, is a quite efficient way of strengthening, which is widely used abroad. Assessment of an adhesive as a suitable product for structural use must take into account the design spectrum of loads, the strength and stiffness of the material under short term, sustained or cyclic loads and the effect on these properties of temperature, moisture and other environmental conditions during service Mays. Concern regarding the durability properties of adhesive joints has meant that resistance to creep, fatigue and fracture are considered of greater importance than particularly high strength. Experimental and theoretical studies about adhesive bonding, as the method of building structures strengthening, using building-up of cross-section, were firstly carried out in midst of XX century. Today, in world practice, the application of the adhesive bonding for strengthening of building structures is widely used.
