Cement was selected as CEM I 32.5 Portland cement. The water-to-cement ratio was chosen as 0.5. Figure 3 demonstrates the slump test results. The workability of the concrete produced by adding WGP increased as the waste rate increased. Accordingly, there was an increase in slump values. It is seen that the slump value increases as the recycled glass ratio increases. On the other hand, when all ingredients were replaced with glass, the slump value significantly decreases. Madandous and Ghavidel obtained an 80 mm slump in their study with the addition of 5–20% WGP. In this study, it is seen that the slump value is 200 mm, since the additional WCP is 50%. It can be said that the results are similar to the literature [35].

Three types of tests were performed in order to evaluate the performance of the concrete with recycled glass. A compression test was performed on 15 × 15 × 15 cm cubic samples while splitting tests were conducted on 10 × 20 cm cylinder samples. Furthermore, bending tests were performed using 10 × 10 × 40 cm samples. Three repetitions were completed for each mix and each test. Compressive ability is the capability of a specimen to decline load under pressure. The CST was performed according to ASTM C39/C39M (C39&C39M A, 2003). In this test, specimens have dimensions of 150 mm × 300 mm. In this experiment, concrete specimens were subjected to constraint lengthwise load at a level in the offered as concerns the specimen fractures. At that point, the compressive capability was estimated from the critical failure strength separated by the part of the specimen. To provide the tensile strength of concrete where compactor load is performed in anticipation of examples unravel caused by expansion of tensile force in concrete as ASTM (Designation, 1976). In this way, cylindrical examples are divided through the vertical dimension.
