A mixture of cement, fine aggregate and coarse aggregate is known as concrete. It plays an important role in infrastructure development like buildings, bridges and industrial structures etc. Long term performance of buildings without deterioration helps economics of nation. High performance concrete (HPC) is a concrete which shows special performance than conventional concrete. This leads to usage of admixtures to improve concrete performance. On the other side cost of concrete ingredients plays vital role, this leading to usage of alternative materials which is economic in its production. This requirement made the investigators to find new replacement for concrete ingredients which should improve long term performance and stability of structures.  This research focuses on  strength and durability characteristics of M60 concrete with partial replacement of sand with ROBO Sand (crusher dust) and cement with Ground Granulated Blast furnace Slag (GGBFS), it is a byproduct in manufacture of iron in steel industry, usage of these replacement materials are more eco friendly. To study the strength and durability characteristics the following properties should be studied such as Compressive strength, Chloride penetration (RCPT test), Permeability (Sorptivity test), Stress strain, Acid resistance. As a part of study strength characteristics were studied by testing compressive strength of cubes. It is found that different percentage of replacement of cement with GGBFS and sand with ROBO Sand helped in improving the strength of the concrete more over equal to normal mix concrete.
