Experimental Study to Enhance Mechanical Strength Properties of Cement Concrete with Fly Ash and Natural Fibers
Journal Title: Saudi Journal of Engineering and Technology - Year 2018, Vol 3, Issue 6
Abstract
Abstract: The production and consumption of building materials have increased to leaps and bounds in the past few decades due to tremendous increase in population. As the production of building materials gets increased, generation of waste materials such as fibers, granules, ashes, effluents etc. also gets increased. Nowadays wastes of different types are being used effectively in concrete either partially and fully which helps in making of green concrete. Fiber reinforced concrete is a special type of concrete in which natural or synthetic fibers with different aspect ratios are used to eliminate or reduce crack formation and to improve various mechanical strength properties when mixed along with fly ash, silica fumes etc. in optimal dosages. In order to study the influence of waste on various strength properties of cement concrete, different dosages of cement are replaced with fly ash and also with coconut fiber or wollastonite fiber were added. The compressive strength, split tensile strength and flexural strength were experimentally evaluated and modulus of elasticity was empirically determined. Based on the test results, the concrete with 20% replacement of cement with fly ash and fiber revealed effective results when compared to concrete without fiber. Coconut fiber along with minimum dosages of fly ash has greatly improved the flexural strength on the other hand it reduces other mechanical properties at higher dosages. Combination of Wollastonite fiber with fly ash helps in the improvement of overall mechanical strength of cement concrete. Keywords: Cement Concrete, Fly ash, Coconut fiber, Wollastonite fiber, Mechanical strength.
