This research was conducted to investigate the utilization of carbide welding waste as a cement mixture on the compressive strength of concrete with a target quality of Fc 25 MPa. The test specimens were cylindrical, with a diameter of 15 cm and a height of 30 cm. Concrete mixtures incorporated carbide welding waste as a partial cement substitute, with variations of 5%, 7%, and 10%, compared to a conventional control mixture based on cement volume. A total of 16 cylindrical specimens were prepared. Compressive strength tests were conducted at 7 and 28 days. The designed concrete strength was Fc 25 MPa. The results showed that the use of carbide welding waste in concrete mixtures led to a decrease in compressive strength at 7 days compared to concrete without waste. However, at 28 days, compressive strength increased significantly, especially at certain percentages. At the optimal percentage, carbide welding waste was proven to improve the compressive strength compared to normal concrete, thus demonstrating its potential as an effective cement mixture
