production of manufacture sand circuit

As a raw material industrially produced sand is much more inexpensive than cement The price of manufactured sand can also be lower compared with natural sand which decreases the production cost of the concrete even further If we consider the fact that natural sand sources are getting scarcer especially close to urban areas transportation costs can be considerable if the sand has to be
