Abstract
In today Construction industries High performance concrete which allowing a reduction in the area of reinforcement needed in certain applications. Due to impose forces by external restraints concrete is significantly bleeds, plastic settlement, thermal and shrinkage strains and stress concentrations even distributed micro-cracks propagate, coalesce and align themselves to produce macro-cracks under an applied load. When loads are further increased, conditions of critical crack growth are attained at the tips of the macro-cracks and unstable and catastrophic failure is precipitated. Under fatigue loads, concrete cracks easily, and cracks create easy access routes for deleterious agents leading to early saturation, freeze-thaw damage, scaling, discoloration and steel corrosion. Evaluating the performance of concrete using different type of fibres is studied in the present paper. Moreover using varying percentage of fibbers which may lead to variation in strength of the concrete hence it has to be assessed. Practical preparation of concrete mixes (M50) for various fibers and also with varying % (0.25%, 0.50%, 0.75%, 1%) of fiber proportions w.r.t volume of concrete is done.
