Abstract
Abstract - The infrastructure needs of our country is increasing day by day and with concrete is a main constituent of construction material in a significant portion of this infra-structural system. It is necessary to enhance its characteristics by means of strength and durability. It is also reasonable to compensate concrete in the form of using waste materials and saves in cost by the use of admixtures such as fly ash, silica fume, etc. as partial replacement of cement. Fiber reinforcement is commonly used to provide toughness and ductility to brittle cementitious matrices. Reinforcement of concrete with a single type of fiber may improve the desired properties to a limited level. A composite is termed as hybrid, if two or more types of fibers are rationally combined to produce a composite that derives benefits from each of the individual fibers and exhibits a synergetic response. The composite matrix that is obtained by combining cement, Fly ash, aggregates and more than one type of fibres is known as “Hybrid Fiber reinforced concrete”. The fiber in the cement fly ash based matrix act s as crack- arresters, which restrict the growth of micro cracks and prevent these from enlarging under load. The experimental work has carried out to study the comparison between hybrid fiber reinforced concrete with class ‘c’ fly ash (20% replacement of cement) and hybrid fiber reinforced concrete with class `F’ fly ash (20% of replacement of cement). A M30 Grade of concrete mixture were designed. This study reports the feasibility of use of steel fibers and palm fibers with class C and class F fly ash content on structural properties such as cube compressive strength, cylinder split tensile strength, and beam flexural strength test. Index Terms – hybrid fiber, class C flyash, class F flyash, palm fiber, steel fiber Abstract - The infrastructure needs of our country is increasing day by day and with concrete is a main constituent of construction material in a significant portion of this infra-structural system.
