Q1: Is there an official classification for what can be called manufactured sand? There is no official definition for manufactured sand. Actually, there is not even a unified name since the product also goes by the name crushed sand, artificial sand and M-sand. Still to call sand manufactured sand it should be purpose-made.

Crushed sand is made artificially by crushing large igneous rocks, granite, and other stones. A fixed sieve provides homogeneity in the sand, while proper production processes decrease the chance of adulteration. To protect natural resources, crushed sand is produced as an alternative to fulfil construction needs.
