The sand which is produced artificially by crushing the stones like granite and sandstone in a quarry is referred to as manufactured sand or in short, we call it M-sand. Some other words which are used for M-sand are crushed sand or artificial sand or Robo sand. Nowadays, due to the huge demand for sand in the construction industry, all our

We often refer to all small, loose stones as “gravel.”. But actually, there is a fundamental difference between gravel and crushed stone. Gravel is a material of naturally occurring loose stone chunks with rounded edges. You can find it occurring naturally, perhaps in a gravel pit or river. Crushed stone, on the other hand, is manufactured.
