Many concrete mixes with different percentages of glass waste powder as a partial replacement to cement (10%, 15%, 20%, 25%, and 30%) were prepared. The results show that the glass waste powder considered as a natural Pozzolan class (N) according to ASTMC618. Many tests were conducted on this powder including, chemical analysis, pozzolanic activity index tests, and the remaining content on sieve of 45 microns. The glass waste was collected, crushed, and grinded for 10 minutes to produce a powder with fineness higher than that for cement of about 7340 cm2/gm. This investigation includes the use of glass wastes after recycling to produce High Strength Eco-Friendly Concrete.
