Sand

Industrial sand and filling sand

A product of nature
Sand is a natural, demolition material made of rocks. With natural resource mining, a distinction is made between:
- industrial sand
- sand for embankments and other applications such as drainage

Industrial sand
This sand has a somewhat larger grain and is used in the production of concrete and masonry mortars, bitumen roads and bricks.

Filling sand
This sand is used as a filling material for building sites and the building of roads.

Sand grains
In geological terms, sand derives from grains ranging from 63 micrometer up to 2 millimeters, grains which are larger than 2 mm are called gravel. Sand which is used for the making of concrete consists of grains up to 8 mm. Therefore, a mixture of sand and fine gravel is called mortar sand.

Sand classification installation
In order to be able to use sand in concrete, the sand needs to be cleaned and sorted. This is done with a sand classification installation. By using a precise range or recipe of industrial sand (which is used in the production of concrete and masonry mortars, bitumen roads and bricks) the amount of concrete is precise and efficient and the maximum strength is guaranteed.
