Abstract: Fibre reinforced concrete (FRC) is a significant achievement of modern construction.
Fibres increase the ductile capacity of concrete by enabling it to undergo large deformation
before failure. The tensile strength of concrete is increased whereas it would otherwise only be
strong in compression. Although FRC has several advantages, the use of steel fibres means it
only provides a little contribution towards sustainability; therefore a shift towards new and
innovative building materials is an urgent necessity. Most manmade fibres such as steel,synthetic or polymer are industrially manufactured and widely used. Such fibres are non-
degradable, non-renewable and expensive. In this research, natural and innovativebiodegradable fibres, their preparation and properties and interaction with concrete have been
highlighted. Agricultural fibres viz. rice and wheat straw have been used. Rice and wheat are a
staple food all over the world. After harvesting the commercial crop there remains huge
quantities of straw produced. This straw has generally been seen as a waste product and
disposed of since it has a very few economic benefits. One of the major problems of today is the
disposal of straw by open air burning and its impact on air pollution has been well documented.
Thus the wastage of straw could be minimised if a viable use for it can be found in the
construction industry. Being a relatively new material, in this research, the chemical and physical
properties of agricultural fibres have been studied. The influence of the addition of fibres in both
fresh and hardened concrete has also been investigated. The findings present an interesting
insight into agricultural fibres. Due to its easy availability and low-cost, straw has the potential to
be a promising bio-based construction material.
