Listed below are few of the advantages of manufactured sand or robo sand:
– Robo sand contains no organic, harmful impurities, hence it has a huge improvement in strength of concrete at same cement content
– Gradation of particles can be controlled during the production of robo sand
– Due to the gradation being controlled, there is no wastage due to oversize materials
