this project's inquiry, concrete may become high dense while using robo sand and it gets excellent workability with GGBS as well as carbon content as heat of hydration will gets reduced. Key Words: compressive strength, tensile strength and flexural strength. GGBS (Ground Granulated Blast Furnace Slag), Robo sand (M-sand). 1.
The Romans used an early type of concrete made with natural pozzuolanic cement more than 2,000 years ago. Today, Portland Cement Concrete is the most important material of construction.

Using different proportion of this robo sand along with sand the required concrete mix can be obtained. Replacement of natural fine aggregate with artificial fine aggregate by 20%, 40% 60% and also finding the compressive Strength of that concrete cube This Project presents a review of the different alternatives to natural sand in
different mixes of concrete grade M30 namely CAC(Conventional Aggregate Concrete), concrete mix manufactured by altering 0%, 10%, 20%, 30%and 40% of cement with Steel Slag powder proportions and by using the substitute ROBO sand as fine aggregate in proportions in all 5 subsituted samples. After the 28days curing done for specimen the
workability of the concrete. Mix Design: The concrete mix is designed as per IS 10262 – 1982, IS 456-2000 and SP 23 for the conventional concrete and finally 0 to 30% river sand has been replaced by ROBO sand and 40 to 60% cement replaced with GGBS by volume.
