For long history, large volume of sand has been produced from alluvial deposits. However we are now experiencing a global shortage of natural sand, and environmental pressures, costs and a shortage of this type of deposit has necessitated the manufacture of sand from quarried material. Construction aggregates also known as crushed stone, sand, sand gravel have been played important role in infrastructure construction and fundamentally improved human’s security, mobility and enhanced mankind’s life quality. It is crucial to produce manufactured sand and aggregates for highway, railway, building construction application. XSM is world leading sand making production line supplier. Industrial sand is really a term ordinarily applied to high purity silica sand items with closely controlled sizing. It’s a extra precise solution than prevalent concrete and asphalt gravels.Silica is definitely the name provided to a group of minerals composed solely of silicon and oxygen, the two most abundant components within the earth’s crust. In spite of its easy chemical formula,SiO2, silica exists in many different shapes and crystalline structures. Found most commonly within the crystalline state, in addition, it occurs in an amorphous kind resulting from weathering or plankton fossilization. Gravel sand , the other important construction sand, is typically substituted for natural sand and gravel,particularly in more densely populated areas in the Ghana.Crushed gravel sand remains the dominant option for construction sand use. Increasingly, recycled asphalt and portland cement concretes are becoming substituted for virgin sand,despite the fact that the percentage of total sand supplied by recycled components remained really little.
