Abstract

An attempt has been made to use waste foundry sand (WFS) in concrete. Glass fibres are added to the concrete forming fibre- reinforced concrete (FRC), to improve its ability to absorb energy and deformation before failure, and behave as a ductile material. Glass fibres with an aspect ratio of 60 need to be used for improving the impact resistance of the concrete. Plant-based natural fibres are low cost renewable materials which can be found in abundance in many countries. Studies have shown that hybridisation of natural fibres with synthetic fibres helps in improving the properties of concrete. Hybrid fibre reinforced concrete (HFRC) need to be manufactured by maintaining a constant dosage (1%) of glass fibre and by varying the proportions (0%, 0.2%, 0.4% & 0.6%) of coir fibre. The present work started by determining the basic properties of materials and mix design for M25 was carried out. Mechanical properties of HFRC with WFS have to be studied and optimum dosage of hybrid fibres has to be found. For that optimum dosage, performance evaluation of beam need to be studied.
