Abstract

Concrete is the most widely used construction material because of its specialty of being cast into any desired shape. But it is well known that conventional concrete does not meet many functional requirements such as tensile strength, resistance to cracking, permeability to liquids, chemical attack, etc. These deficiencies have led the researchers to investigate and develop a suitable material which could perform better in areas where the conventional concrete poses several limitations. The recent development in concrete technology has resulted in the arrival of new products such as High Performance Concrete, Fibre Reinforced Concrete, etc. The main requirements of disaster resistant structures are good ductility and energy absorption capacity. Conventional concrete does not fulfill all the requirements of earthquake resistant structures. Fibre reinforced concrete possesses a high flexural and tensile strength, improved ductility, high energy absorption than the conventional concrete against dynamic loads. Because of the advantages of FRC, it can be used in earthquake resistant structures. When the concrete is reinforced with randomly dispersed fibres it prevents micro cracks from widening. The combination of various types of fibres in a mix results in the formation of hybrid fibre composites. One type of fibre improves the properties of fresh concrete and prevents early shrinkage cracks while the other type of fibre contributes to the improvement of strength and ductility of hardened concrete. The scope of the present study is to investigate the influence of different combination of hybrid fibres. The investigation was carried out on two different types of fibres namely round crimped steel fibres and polypropylene fibres. The mechanical properties such as compressive strength and split tensile strength were investigated in the laboratory tests. The reinforced concrete structural elements have been designed with M20 grade concrete.
