Abstract: With increased depletion of natural construction materials, alternative means must be sought for substitution of the same. Excessive energy consumption in the production of construction materials, environmental setbacks and debris disposal are some of the other burning issues fuelling the need for reuse of the raw materials. With the need of natural sand, there is an urgent need for a product that matches the properties of natural sand in concrete. Construction- Demolition waste and ROBO Sand are some of the upcoming resources which enables effective replacement of the materials of mineral origin. In the present work, natural coarse aggregate was replaced with recycled coarse aggregate and river sand was replaced with ROBO Sand in different percentages in plain cement concrete. Different strength test were conducted with combination of ROBO Sand and recycled aggregate to study the effect of these two materials on strength Concrete with a characteristic compressive strength of 30 N/mm2 (M30 grade), was used for our study. In total, 16 sets of 6 cubes each were cast and tested.
