Comparative Study on Fibre Reinforced Concrete and Nominal Concrete

Concrete is weak in tension and possesses high compressive strength, stiffness, low thermal, brittle character and toxicity so it is have provided a technical basis for improving such deficiencies. The use of fibres is to improve the characteristics of construction materials. Fibres are small pieces of reinforcing materials added to a concrete mix. In addition with the most common fibres used is namely steel, glass, asbestos, etc. When the loads imposed on the concrete approach that for failure, crack will propagate, sometimes rapidly, fibres in concrete provides a means of arresting the crack growth. If the modulus of elasticity of fibre is high with respect to the modulus of elasticity of concrete or mortar binder the fibre helps to carry the load, thereby increasing the tensile strength of the material. Fibres increase the toughness, the split as well as compressive strength, and reduce the creep strain and shrinkage of concrete.In this paper, the aim of the study is to comparison between properties of fibre reinforced concrete at different percentage 1% to 3% with respect to 7days and 28days fresh water curing with nominal concrete at weigh batching and volume batching method. Concluded that the addition of fibres improves ductility of concrete and its post-cracking load carrying capacity. Split tensile strength of concrete goes on increasing as fibre content is increases. The compressive strength of concrete by weigh batching is higher as compared to volumetric batching method.
