Experimental Study on Concrete by Adding Polyester Fibres

There are increased innovations in the field of concrete because there are endless opportunities for innovative materials, techniques, applications, and design. Today’s construction industry is looking for cost-effective materials to improve the strength of concrete structures. As a result, an attempt has been made in the current research to investigate the impact of adding polyester fibres (Recron 3s) to concrete. Fibres improve concrete's tensile and flexural strength, fatigue properties, durability, shrinkage properties, impact and erosion resistance, and serviceability. Polyester fibres (Recron 3s) are micro fibres; they contribute to enhancing the resistance of concrete to shrinkage and cracking and also help to improve mechanical properties such as the flexural / split tensile and transverse strength of concrete along with improvements in abrasion and impact strength. An experimental study was done using a M30 mix design. Polyester fibres (Recron 3s) were used in the concrete with varying dosage rates of 0.50 kgs / cu.m – 2.00 kgs / cu.m. This study describes the enhancement in the strength of the M30 grade mix concrete by the addition of polyester fibres (Recron 3s) in the proportions of 0.5, 1, 1.5, 2.0kg/cu.m, and M30 concrete with varying dosages of the polyester fibres (Recron 3s) were mixed and cast.
