Glass should be ground up into sand sized particles and used for a 1 to 1 replacement for increasingly rare and expansive river sands for concrete aggregates. Desert sand is too rounded to be of any use in concrete you must have angular river sands or offshore sand bar materials which are just river sands that made it down dip to the sea.
Glass of any color when ball milled or hammer milled comes out angular not rounded it’s perfect for concrete as it’s pure silica as is. More pure that even the best river as sands. You can also melt glass and make structural blocks with it Th at replace cement blocks or bricks. But crushing it to sand size is the clear winner.
Remember kiddies sand is a grain size not a composition.

Crushed sand is better.
