How Silica Sand Is Different From Regular Sand. Regular sand, also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for concrete applications can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium ...
· Results obtained in our lab are usually around an index of 110, best-case using HD silica with extremely high BET and CTAB values around an abrasion index of 120. Conclusion The test program conducted shows that it is possible to mix ENR compounds without much hassle but yielding good to excellent compound performance.
