Abstract
The demerits of plain concrete are its lesser tensile strength, not significant ductility and poor resistance to cracking. Due to propagation of internal micro cracks in plain concrete causes decrease in tensile strength, hence leads concrete to brittle fracture. Addition of fibres behaves like crack arrester and enhances the dynamic properties of concrete. In India natural fibres such as bamboo, coir, jute, sisal, pineapple, banana, ramie etc are high available. Jute is a useful natural fibre for concrete reinforcement due to its easy availability and low cost. In this research, the experiments related to Jute fibre reinforced concrete (JFRC) are done by taking different fibre percentage and the compressive strength and modulus of rapture value observed. This JFRC can replace plain concrete and wood in many cases for example in door and window panels, inclined roof slabs, partition walls etc
Highlights
In the nineteenth century, when concrete came into existence, it was used merely as a covering material to steel, to safe guard against the weathering effects
The five types of Jute fibre reinforced concrete (JFRC) denoted as JFC-I, JFC-II, C-III, JFC-IV, JFC-V are prepared by adding different percentage jute, shown in Table-IV
The Compressive strength results of cubes and cylinders, Modulus of Rapture values of beams and cylinders for continuously oriented JFRC are given in Table-V and for randomly oriented JFRC are given in Table-VI
Summary
In the nineteenth century, when concrete came into existence, it was used merely as a covering material to steel, to safe guard against the weathering effects. More researchers devoted themselves to investigate the different properties of concrete and its constituent materials. As the plain concrete is low in resisting cracking due to its lesser tensile strength and poor ductility, addition of small fibre distributed closely and uniformly can enhance the dynamic properties by arresting the cracks. The natural fibres like ramie, coir, bamboo, sisal, jute, banana, pineapple etc are highly available in India. Among these due to low cost and availability, jute can be used as fibre reinforcement in concrete. It can replace partially or fully the glass fibre.In this current study an attempt has been made to check the influence of Jute Fibre with 0.15%, 0.25%, 0.35%, o.5% by weight of concrete mix on properties like compressive strength and modulus of rapture. The tests are carried out as per IS codes recommendation
