An Experimental Investigation on The Mechanical Behaviour of Polypropylene Fibre Reinforced Concrete Using Ferrous Slag as A Partial Replacement of Fine Aggregate

Abstract

Globally construction industry has enormous growth year by year. This leads to increase the need for construction materials. We are taking the materials from natural resources because of this natural resource depletion occurs at a faster rate. Also, this affects the environment. Cement production leads to higher amount of CO2 emission similarly depletion in river sand leads to ground water problems. So we have to find some alternate materials to conserve the earth for next generation. The faster industrial growth generates large amount of industrial wastes. Industrial waste material management is such a challenging area. Handling and disposal of industrial waste is a big issue for every country around the world. Ferrous slag is considered as an industrial waste which is obtained from iron smelting process. To minimize the environmental problems ferrous slag is used in concrete as a partial replacement of fine aggregate. Concrete is strong in compression and weak in tension. Using Polypropylene fibre we can increase the tensile strength of concrete. Mainly polypropylene fibre resists the micro plastic shrinkage cracks. Here polypropylene fibres added as micro reinforcement. But not much research has been carried out to study the combined behaviour of ferrous slag and Polypropylene fibre. The percentages of replacements of sand by granulated ferrous slag are 0%, 20%, & 50% and also the fibre dosage is maintained as constant 0.5% of cement. This research focused on the combined behaviour of ferrous slag and polypropylene fibre in study strength and transport properties.
