Crushed sand is a mixture of aggregate particles less than 5 mm in size obtained by crushing, or crushing from natural rocks with a solid structure. Crushed sand is produced by crushing natural stones with a solid structure to the required grain sizes for concrete and mortar production.

Currently, natural sand is increasingly scarce, the use of crushed sand material to replace natural sand is being encouraged to apply. Detailed instructions on the use of crushed sand for concrete production and technical requirements for crushed sand have been issued in a number of standards such as: TCVN 9205:2012 “Crushed sand for concrete and mortar”; TCVN 9382:2012 “Instructions for choosing concrete composition using crushed sand”. In addition, the mixing of fine sand and crushed sand to achieve the modulus of magnitude for concrete can refer to TCVN 10796:2016 "Fine sand for concrete and mortar".

Specifications of artificial sand:

According to TCVN 9205-2012 Crushed sand for concrete and mortar:
Dry sand: when the modulus of magnitude is greater than 2.0 - 3.3.
Fine sand: when the modulus is larger than 0.7 - 2.0.
The content of dust, mud and clay is not much more than 2%. The chloride content in acid is not more than 0.01% (for concrete used in prestressed reinforced concrete structures) and 0.05% (for normal concrete). Crushed sand that meets the necessary standards is a sand with few impurities, thick particles, high permeability, easy to stick in concrete and mortar mixture.

Materials for the production of Artificial Sand:

Any rocks that intensity good, stable, can be used as raw construction materials can act as raw materials to produce artificial sand, such as limestone, granite, sandstone, basalt, rock pebbles, hill pebbles, river pebbles, sieves, dust...

Applications of artificial sand:

- Most hydropower projects use more than 90% of crushed sand to make concrete mix.
- Construction of highways, pouring concrete columns, concrete culverts.
- Crushed sand is becoming one of the familiar materials when gradually replacing natural sand in many construction projects, and will soon become popular and solve the serious sand shortage problem when there is no natural sand. Natural sand on the river is seriously lacking, construction works spring up like mushrooms after rain.
