Ground glass pozzolan is a type of pozzolanic material that is made from recycled glass. It is produced by grinding waste glass into a fine powder and is used as a supplementary cementitious material in concrete. It is a sustainable alternative to traditional pozzolans such as fly ash and silica fume, as it is made from recycled materials. https://www.globalinsightservices.com/reports/ground-glass-pozzolan-market
