Construction sand, sand drying subhead, washed sand mesh points described in detail, drying sand, mica sand: Lin sand is a natural stone in its natural state, the force of the water long repeated collision, friction, and its ingredients more complex, has a certain surface smoothness, non-metallic impurity content and more ore. River sand particles sleek, relatively clean, wide source; no taste of river sand, sea sand and salt flavor. Sand for the construction industry has Zhuo contribution. But the sand on the contrary, often mixed with sand and salt shells, most of the sand containing an excess of chloride ions, which can corrode steel reinforced concrete, resulting in damage to the building structure, to a certain extent, will shorten the safe use of the building lifetime. Construction sand, use dry sand - sand after the screening, the main raw material used as external wall insulation mortar, such as adhesive mortar surface mortar river to wash sand is the main raw material. Intensity similar to quartz sand to make mortar. Since the skeleton or fill in concrete loose granular material. Properties, a melting point of 1730 degrees Celsius. Quartz sand (powder) and water are two sub-dry method of production, various common denominator sand specifications: 6-10M, 10-20M, 20-40M, 40-80M, 80-120M, 120M, 200M, 260M, 325M , 600M. There is also special sizes according to customer requirements and processing required particle size distribution generally be processed. Building sand purposes - the manufacture of glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, casting and other aspects of its use in the construction of a strong acid etching medium capacity, extracting acid and acid-resistant concrete mortar. Construction sand, building sand dry sand, dry sand
