GPSS has a pH of 11.72 and a TDS of 768 mg/L, whereas natural river sand has a pH of 7.40 and a TDS of 452 mg/L. In comparison to NRS sand, GPSS has a higher pH value and lower TDS. However, it has very comparable qualities when used to make mortar or concrete, therefore GPSS can be used as a substitute for natural river sand.

Abstract. Manufactured sands are produced by crushing rock deposits to produce a fine aggregate that is generally more angular and has a rougher surface texture than naturally weathered sand particles. Manufactured sands can also contain significant quantities of rock dust. As natural sand deposits become depleted near some areas of …
