There are 3 Types of Sand Used in Construction:
Natural sand: under the action of natural conditions, the rock will be broken, weathered, sorted, migrated and piled (settled), forming rock particles with a history of less than 4.75mm. Note: Natural sand includes river sand, lake sand, mountain sand and purified sea sand, but does not include soft and weathered particles.
Artificial sand: it is made of rocks, pebbles, mine waste rocks and tailings by mechanical crushing, shaping, screening, powder control and other processes after soil removal, and its grading, particle type and stone powder content meet the requirements and its particle size is less than 4.75mm. Note: Machine made sand does not include soft and weathered particles.
Mixed sand: sand mixed by machine-made sand and natural sand in a certain proportion
