AN EXPERIMENTAL INVESTIGATION OF TERNARY BLENDED HYBRID FIBER REINFORCED CONCRETE (MK: FA: GGBS): STEEL & POLYPROPYLENE FIBERS

Abstract

In recent times, the world is taking into a part of challenging construction by using hard structures and high strength concretes. The proposed procedure deals with the experimental examination to find the mechanical properties of ternary blended concrete with hybrid fibers. Utilizations of mineral admixtures, such as, Fly Ash (FA), Metakaolin (MK) and Ground Granulated Blast Furnace Slag (GGBS) are efficient to increase the strength and make sturdy for high strength concrete. Mechanical behavior of ternary blended concrete is prepared by high rates of ternary mixes like MK, FA, GGBS (10%-30%) and hybrid fibers (steel and polypropylene) with different volume parts (Steel:0.5-2%; PP:0.1-0.5%) are explored. The specimens are set up by various evaluations of concrete, for example, M20, M50, and M60 and furthermore shifting rates of ternary mix and fibers. The test examinations explored the proposed specimens and find the compressive strength, split tensile strength, and flexural strength. The proposed ternary blended concrete with hybrid fibers upgraded the mechanical properties and optimal strength.

Flexural Behavior of the Structural Concrete Reinforced With Steel and Polypropylene Fibers

“…Concrete is one of the most used elements in the construction industry, due to the contributions of its physical and mechanical properties such as its versatility, workability, durability and resistance [1] [2]. editor@iaeme.com Adding fibers to concrete to decrease the expansion of failures, due to weakness in tension and drying contraction [3], not only develops compressive, tensile and flexural strength, but also provides adequate response before and after cracking.…”
