PAST INVESTIGATIONS ON MECHANICAL AND DURABILITY PROPERTIES OF HYBRID FIBER REINFORCED CONCRETE

In recent years fibers has been widely utilized for strengthening of concrete structures due to its high tensile and flexural properties. In this paper, an introduction is given on the properties of different fibers used for structural applications. Moreover, a brief review of the past investigations on different fibers and the use of metallic, natural and synthetic fibers on improvement in hardened and durability properties of concrete are also highlighted. This paper shall focus on literature review on strength and durability properties of hybrid fibers Steel/polypropylene/glass and carbon fiber reinforced concrete.
