Comparative Analysis of Fibre Reinforced Concrete: A Study on Mechanical and Durability Properties

The paper discusses the “fibre-reinforced concrete (FRC) to enhance mechanical strength and crack resistance and durability of the concrete that is brittle in nature and possesses low tensile strength. Polypropylene fibres (FRC) and steel of (1%-0%), (0.75%- 0.25%), (0.5%- 0.5%), (0.25%- 0.75%), (0%- 1%) respectively in different proportion were compared-actively analysed to determine the effects on the workability, compressive strength, flexural strength, and split tensile strength at different curing periods and resistance to chemical attack. Discovery has revealed that the character and proportion of the kind of fibre significantly influence the fresh and hardened characteristics of the concrete and steel fibres are superior regarding mechanical strength. Contrast made crack resistance and sustainability in synthetic and natural fibres also better. This paper highlights the reality that FRC can address the structural limitation of the normal concrete. It examined the possibility of using the quarry dust as an alternative to natural river sand in FRC which is eco-friendly considering that quarry dust is a by-product of stone crushing. M40 grade concrete mix was prepared using polypropylene (PP) and steel fibre in 0 to 1 per cent proportions regarding the mass of cement. The project identified the physical and chemical compatibility levels of these fibres with concrete, and identified the workability (slump test), compressive strength, flexural strength, and split tensile strength of such fibres after 14, 28 and 56 days of curing.
