Abstract

The use of concrete containing high volume fly-ash (HVFC) has recently gained popularity as a resource efficient, durable, and sustainable option for a variety of concrete applications. If containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. In this research two categories, HVFC with fiber mixture is prepared one containing 40% fly-ash and other 50% fly-ash. For each mixture prepare M20, M25 and M30 grade concrete with fiber. The HVFC with fiber mixture reached similar to the ordinary concrete mix, due to the pozzolanic properties of the fly-ash and the lower water-cement ratio. The setting time for the HVFC with fiber mixtures was approximately six to seven hours longer than those of ordinary concrete mix. The drying shrinkage of concrete is directly influenced by the amount and the quality of the cement paste present. It increases with an increase in the cement paste-to-aggregate ratio in the concrete mixture, and also increases with the water content of the paste. Clearly, the water-reducing property of fly ash can be advantageously used for achieving a considerable reduction in the drying shrinkage of concrete mixtures. In HVFC with fiber mixture the heat of hydration is slower that raise the temperature difference between the interior and exterior concrete should not be more that is good for avoiding thermal cracking and presence of fiber the bonding of concrete is good, so in this concrete, the cracks are not easily developed. Use of steel fiber in concrete its increase the tensile strength of concrete. Due to the high volume of fines and low water content, fresh concrete mixtures of the HVFC with fiber system are generally very cohesive and show a little or no bleeding and segregation They show excellent pump-ability and workability at slumps as low as 125 mm, however, more-then 125 mm slump values may be specified with heavily reinforced structures. Consequently, the surface finish is usually smooth pleasing and without honeycombs and bug-holes. For countries like China and India, this technology can play an important role in meeting the huge demand for infrastructure in a sustainable manner
