Silica Sand an overview ScienceDirect Topics
The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g The material usually contains more than 997% SiO 2, with absorbed water being at a negligible level (01%)
