Abstract: Provided herein are processes for preparing glass powder product, the process including steps of: providing a crushing waste glass; sorting the crushed waste glass in a primary air classifier to provide a first stream and a reject stream, the first stream comprising a pulverized glass within a predetermined first particle size range and the reject stream comprising crushed waste glass excluded from the first stream; separating the reject stream based on size to provide a coarse stream and a fine stream, the fine stream having a predetermined second particle size range; and milling the first and fine streams to provide the glass powder product. Glass powder products, as well as systems for producing such glass powder products, are also provided.

Abstract: Provided herein are processes for preparing a glass powder pozzolan product, the process including steps of: providing a crushed and clean waste glass; sorting the waste glass post pulverization through a process to take a coarse stream; adding a fine stream collected in the process and milling the coarse and fine streams to provide the glass powder pozzolan product. Glass powder pozzolan products, as well as systems for producing such glass powder pozzolan products, are also provided.
