Specific types of sand are used in the manufacture of glass and as a molding material for metal casting. Other sand is used as an abrasive in sandblasting and to make sandpaper. Sand was used as early as 6000 B.C. to grind and polish stones to make sharpened tools and other objects. The stones were rubbed on a piece of wetted sandstone to hone ...
Nov 10, 2015 The study reported that while the physical characteristics of manufactured sand are similar to riverbed sand, the concrete made has higher compressive 6-9 and flexure 12-15 strength. The technical analysis showed that manufactured sand is suitable for applications in mixtures such as mortar and concrete.
Another critical issue with manufactured sand besides the fact that the process creates a sand that is dusty, is the concern over getting it in your childs eyes. Because the machines crush the rock, the process also creates angular grain shapes which have sharp or pointy edges. Getting those grains as opposed to sand grains made rounded ...
Only sand manufactured by V.S.I. Crusher is cubical and angular in shape. Sand made by other types of machines is flaky , which is troublesome in working. There is no plasticity in the mortar.
