Construction Stone Chips, gravel stone, crushed stone

 

 

Black stone chips is an important series of stones, different from the ordinary stone we promoted before. Black stone is the best anti-sliding materials for road and airport runway, it has many advantages, such as strong resistance, low crushing value, strong corrosion resistance, strong wear resistance of the adhesion of asphalt, less draught , poor Conductive property, strong compression, strong corrosion resistance, adhesiveness of asphalt, etc.

Harmful impurities and elongated and flaky particles: aggregate contained in clay, silt, fine dust, sulfate, sulfide and organic matter and harmful substances, the content should be in accordance with the provisions of the relevant standards; in addition, the aggregate prohibited mixed with calcined dolomite or limestone blocks. The use of the important engineering concrete crushed stone or gravel, should also be the alkaline activity test, to determine its suitability. The aggregate of elongated and flaky particles in content meet the requirements of relevant standards.
