 · This size can be achieved by using a grinding operation with the help of "Ball Mill" which is generally used in cement industry to grind cement clinker. Several researches show that at the higher age recycled glass concrete (15 to 20 of cement replaced) with milled waste glass powder provides compressive strengths exceeding those of control concrete ( Nassar and Soroushian 2011 ).
