Abstract

This research was performed to investigate the performance of quaternary hybrid fibre reinforced concrete using local materials. Additional cement materials (SCMs) are being included into concrete in the building sector as the result of economic and environmental advantages and improvement of concrete characteristics. But the concrete produced from SCMs is not promising if the impact and dynamic load are brief. Unreinforced concrete has poor tensile strength and low fracture stress capability. Under impact stress, flat concrete suddenly collapses in a fragile way. Fibers are used in concrete to counteract this weakness to enhance mechanical characteristics. In general, steel, carbon and polypropylene fibres are utilised in concrete. However, when the hybrid fibres are combined with two or more combinations, the hybrid composites have more appealing engineering features than the inclusion of one single fibre type in the composites. Because of environmental and structural aspects, fibre hybridization in multiple Portland mixing cement concrete is increasingly significant. In this study, a quaternary mix was suggested as a control mix in which Fly Ash, Rice Husk Ash and Lime Stone Powder were partly substituted with Ordinary Portland cement. Steel, carbon and polypropylene fibres were added to the quaternary mixed concrete mix, in mono and hybrid form. The twenty-six various quantities of fibre in the concrete mix, including control concrete, were examined. The experimental study was split into three stages. During the first phase, at the age of 28, 56 and 90 days mechanical characteristics such as strength of compression, splitting of tensile strength, bending strength and impact resistance of mono- and hybrid fibre reinforced four-piece concrete were examined. The optimal combination vi was determined in each hybrid fibre combination on the basis of the research. Mathematical models are created using statistical techniques to anticipate their different strengths and compare them with the outcomes of the experiment. In the second phase, the durability characteristics of the quaternary blended concrete, such as water absorption, sorptiveness, acid strength, sulphate resistance and chloride permeability, with optimal mono- and hybrid fibres, were examined. The bending behaviour of the quaternary mixed concrete beams with mono and hybrid fibres was studied in the third stage.
