Strengthening of reinforced concrete structures by external reinforcement with composite materials
Journal Title: Вісник Одеської державної академії будівництва та архітектури - Year 2018, Vol 1, Issue 70
Abstract
Investigations of national and foreign achievements in the rehabilitation and reinforcement of reinforced concrete using composite materials containing fibers with high mechanical strength and use of special epoxy resins are carried out. Composite materials based on glass, basalt, aramid, and especially carbon fibers are considered. The advantages and main disadvantages of the most commonly used composite material based on carbon fibers are noted. Principal schemes of strengthening of the most common types of reinforced concrete bent structures are given. At present, reinforcement of bent reinforced concrete structures by external reinforcement with carbon fiber is the most technically advanced method. In general, the world practice shows a steady growth in the use of composite materials in construction, especially in reinforced concrete structures. It is necessary to recognize the decline of interest in the national research and practical results in this field of science and technology. The generalized conclusions and recommendations are given.
