Glass Fibres, Aramid Fibres, Eco-Friendly, Flexural Strength, Admixture.Abstract
Plain concrete has two deficiencies, low tensile strength and low strain at fracture. The present trend in concrete technology is towards increasing the strength and durability of concrete to meet the demand of the modern construction, and for that we add fibres in concrete. Fibres such as steel fibre, glass fibre, synthetic fibre, natural fibre and organic fibre when added in certain percentage in concrete it improves the strain properties as well as crack resistance, ductility, flexural strength and toughness. If we add glass fibre content of 0.33%, 0.67% and 1% in concrete it is observed that percentage increase in flexural strength after 28 days is 7.31 N/mm2 ,7.59 N/mm2, 7.07 N /mm2 respectively without reinforcement. The aramid, ones being the most effective, the first organic fibre having high tensile modulus and strength. It has 5-10% higher mechanical properties than other synthetic fibres. Hence, an attempt has made in the present investigation to study the flexural strength of aramid fibre in concrete.
