A method of processing cathode ray tube (CRT) glass with waste glass into a pozzolanic mixture includes, receiving CRT glass aggregate, pulverizing the CRT glass aggregate forming an intermediate CRT glass product, fine grinding the intermediate CRT glass product into a powder, receiving waste glass, pulverizing the waste glass forming an intermediate waste glass product, fine grinding the intermediate waste glass product into a waste glass powder, and combining the waste glass powder with the CRT glass powder by weight or volume to form the pozzolanic mixture. The pozzolanic mixture may be used in place of Portland cement in a cementitious mixture.
