Self Compacting Concrete (SCC) is the latest and advanced technology in the field of concrete technology. SCC is an innovative type of concrete, one of which has properties flowable. In this study, one of the innovations in the use of glass bottles as a substitute some cement for SCC. This research was conducted to determine the effect of glass waste powder as partial substitute for cement on slump flow, specific gravity, and the compressive strength of concrete aged 14 days SCC. The mix design used was Okumura’s Simple Mix Design [1], water-per-powder ratio 0.35, and dosage superplasticizer 1%. Variation of glass waste powder 0%, 5%, 10%, 15%, 20%, 25%, and 30% of the weight of cement, the size of the waste glass powder is through the filter no. 100 and stuck in the filter no. 200. The test object in this study uses a cylinder with diameter 15 cm and height 30 cm. The flowability test is carried out when the concrete is fresh. For hard concrete, specific gravity and compressive strength tests are carried out at the age of 14 days. The result of replacing glass waste powder as a substitute for some cement has a significant effect on the slump flow value of 85%. Slump flow in fresh concrete mixture with various glass waste powder 5%, 10%, 15%, and 20% reach the standard [2]. Replacement of glass waste powder as a substitute for part of cement has a significant effect on the specific gravity concrete amounting to 69.6%. Specific gravity concrete in this study fulfills the requirements for structural normal specific gravity[3]. On the compressive strength of concrete aged 14 days, glass waste powder has a significant effect of 86.2%. Compressive strength has a maximum compressive strength of 35.322 MPa, with an optimal percentage of glass waste powder as a substitute for partial cement is 10.464%.
