The need to find new sources of building materials led to examine the using of waste materials resulted from the production plants. This paper investigates using of waste crushed glass as part of cement at 5, 15 and 25% of cement weight . Well graded sand from Zliten quarry was used in the production of concrete. Concrete mixes were produced using w/c ratios 0.4, 0.425 and 0.45. Workability of fresh self-compacting concrete (SCC) and compressive strength at 28 days were tested. Test results showed that fresh concrete was within the range of self-compaction needs, and concrete strength was also satisfied at 28 days. From analysis of test results, it was obviously noticed that replacing part of cement by powder of crushed glass gave good self-compacting concrete at percentages as large as 25% with enough workability and good strength. And this proves that waste glass from plants can be used in the production of self-compacting concrete. As a result this will protect the environment from gas emission from cement plants and provides a new sources building material.
