River Sand For Construction
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size.
We sell river sand in large quantity , we have capacity to supply river sand to all over the world contact us for price and sample .
We are into river sand/vibro sand, armour rock, boulders and aggregates/gravel business in the Philippines. We have more than 18 quarries in the Philippines. We could supply in quantity for local and international markets.
We are supplier and exporter of Silica Sand. Silica Sand * Silica Sand is a type of sand usually available in the form of quartz. It is a hard and crystalline form of mineral components. * Silica sand is the most abundant mineral with the purity more than 99.0%. It is the preferred choice of consumption for various industrial purposes.

Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.
