Experimental Studies on Fibre Reinforced High Strength Concrete as per IRC Guidelines

EasyChair Preprint 8036

Abstract

Concrete as a construction material is widely used in India with annual consumption exceeding 100 million cubic meters. Conventional Ordinary Concrete which is designed on the basis of compressive strength does not meet many functional requirements. So, there is a need to design High strength Concrete (HSC) which is far superior to conventional concrete. It has now become imperative to look for alternatives of constituent materials of concrete. In last few decades, several studies have been conducted to investigate the effect of addition of waste foundry sand as partial replacement of 0% to 40% in the interval of 10% by adding with and without poly propylene fibers to the regular sand in concrete and also Construction and demolitions activities have increased phenomenally for the past two decades. With these construction activities going up, we are falling short for the construction materials, especially aggregates, therefore finding an alternate resource is the need of hour. The construction and demolition waste also partially replacement of 0% to 20% in the interval of 5% by adding with and without poly propylene fibers as per IRC44-2017 for an M50 grade of Concrete. The aim of this study is to evaluate the optimum percentage replacement of both foundry sand and C&D waste by Compressive strength, split tensile strength and flexural strength of concrete for 7, 14 and 28 days.
