Robo sand is one of the most used among such materials to replace river sand, which can be used as an alternative to fine aggregate in concrete. In the present investigation workability and strength of concrete was evaluated by replacement of natural sand by Robo sand in proportions of 0%, 50%, 75%, and is studied

Sea sand and robo sand are the alternate material for exhausting river sand. Sea sand is very cheap in cost and easily available in coastal area but it contains alkali matter and impurities which are not good in concreting. This sea sand can get washed and used for many constructions. Robo sand is the one of the alternate material for river sand.

The concrete is widely used in the construction industry. River sand is commonly used construction material. Natural weathering of rocks results in the formation of river sand, over millions of years. Robo Sand (R.S) which is eco-pleasant serves as a partially substitute material for the depleting river sand.
