Utilization of glass waste powder is an alternative material as a substitute for some cement in SCC concrete because the element contained in the glass waste powder has similarities with cement. Research on glass waste powder as a substitute for some cement using percentage variation that is 5%, 10%, 15%, 20%, 25%, and 30%, with the age of SCC concrete 28 days. The study uses quantitative methods to obtain data on the tensile strength and porosity of the SCC concrete with glass waste powder as a partial substitute for cement. A tensile strength using a cylinder-shaped sample of 150 mm diameter and 300 mm in height with a sample amount per percentage of 4 pieces. The porosity test uses a cylinder-shaped sample of 150 mm in diameter and 300 mm in height with a sample number of each 4 pieces. The results of the study acquired a significant influence of the addition of glass waste powder to strong tensile and porosity of the SCC. Besides, it also obtained the optimal percentage value of the addition of glass waste powder to tensile strength concrete of 5.5% with a maximum value of tensile strength 3.422 MPa. For porosity obtained the optimal percentage value of glass waste powder at 8.583% with a porosity value of at least 9.806%.
