    2019-4-2 · Abstract- River sand is the one of the basic material in the manufacture of concrete. High Performance Concrete (HPC) is a concrete meeting special combinations of performance and uniformity requirements that cannot be always achieved routinely by using conventional constituents and normal mixing. Recently natural sand is becoming very costly because of its demand in the construction industry and BAN of sand mining in rivers. So research for the alternatives of natural sand is going to find in economical way to meet the high performance characteristics. In this path the manufactured sand called ROBOSAND is the new material i.e., arrived in the world of concrete to fulfill the requirements of Natural sand. The other material FLYASH comes from the industries as a by-product which is freely available. Many researches suggesting that the Fly ash is a good replacement for cement. Codes such as ACI are also suggesting that flyash will be useful material to replace cement up to 35%. This present paper mainly focuses on achieving high performance characteristics of concrete by comparing M80 and M90 grades. The strength, workability and Durability properties for both grades are compared by varying the percentages of ROBOSAND with natural sand
