Abstract

In present situation, fine and coarse aggregates have become a rare commodity and efforts are needed to conserve the natural resources which are depleting day by day. Legal complications are also making it difficult to meet the aggregate demand. No-Aggregate Concrete (NAC) is a concrete in which coarse aggregate and fine aggregates have been totally replaced by fly ash. Use of fly ash as partial replacement of fine aggregate in concrete will have no delayed early strength development, but rather will increase its strength on long-term basis. The study of mechanical properties of NAC incorporating chopped carbon fiber of length 6mm to 12mm with varying volume fractions i.e.0.2%, 0.4%, 0.6% by weight of fly ash is done to achieve improvements in mechanical properties. The compressive strength, flexural strength, splitting tensile strength and load carrying capacity of reinforced NAC was examined in this study. Comparison is being done between control NAC and NAC with carbon fibers. The experimental study shows that incorporation of carbon fibers improves the mechanical properties of NAC
