Natural Sand

Natural sand is naturally occurring rock particle with a grain size below 4.75 mm through the artificial mining and screening processes, including river sand, lake sand, mountain sand, desalination sea sand (also called washing sand), but not including soft, weathered rock particles.

natural sand exploiting

The sea sand is usually strictly prohibited to use in architectural decoration field. Although sea sand is clean, it contains high-level salt content that will have a bad impact on the quality of construction projects.  It mainly to see whether the sand contains small marine shells to distinguish whether it is the sea sand.

Mountain sand has a relatively rough surface resulting a good effect for cement attaching, but the components of mountain sand is complex and most of them contain soil or other organic impurities.

River sand is a natural stone generated after a long-term repeated collision and friction under the water force in the natural state. It is one type of non-metallic ores with a complex components, a certain smooth surface but more impurity contents. After the drying and screening processes, river sand can be widely used in a variety of dry mortar production, for example,the insulation mortar, bonding mortar and surface mortar are use washing, drying, grading river sand as the main aggregates. The strength is similar to the mortar made by quartz sand. Therefore,the river sand has an irreplaceable role in construction and decoration fields.
