A STUDY ON THE IMPLEMENTATION OF COMPOSITE MATERIALS ON CONCRETE SURFACES

Abstract

The sustainability of a building is its ability to maintain throughout its existence and the characteristics of its resistance based on how they were designed and executed, without requiring additional maintenance costs. Measures to ensure an adequate durability are chosen based on the environmental conditions and the importance of the building. During the years, concrete structures from all over the world have been severely damaged due to various aggressive environments, which resulted in the deep corrosion and destruction of the structural elements. Of all the tests one of the most promising method is the use of composite materials because those materials have the advantage of not corroding, even in hostile environments. For strengthening and renovation of concrete structures, the most utilized up to the present time is the use of externally bonded beams reinforced with FRP sheet or plate stuck with highly resistant adhesives, which have basic matrix made from a mixture of different epoxy resins. Polymer-based fibers, made of carbon fiber (CFRP) dominates these works, being used both for the issuing of CFRP independent bar and also for obtaining CFRP plates or sheets. The utility of carbon fibers characteristics determined researchers to use them in construction works.
