Abstract
In an era of continuous progress in the field of construction, research is being carried out to develop higher quality concrete. This research aims to analyze the effectiveness of using fly ash as a partial replacement for cement and steel slag as a partial replacement for fine aggregate in concrete. The variations in fly ash replacement used are 0% and 5%, while steel slag replacement is 0%, 5%, 8%, 10% and 12%. Concrete was tested at the age of 28 days by making test samples for each variation in the form of cylinders with dimensions of 15 x 30 cm and blocks measuring 60 x 15 x 15 cm. Tests include compressive strength, flexural strength, and concrete absorption level. The research results showed that the compressive strength of concrete with the addition of 0% fly ash + 0% steel slag was 26.58 MPa, 5% fly ash + 5% steel slag was 20.86 MPa, 5% fly ash + 8% steel slag was 25.57 MPa, 5% fly ash + 10% steel slag was 28.27 MPa, 5% fly ash + 12% steel slag of 28.17 MPa. The flexural strength value of concrete with the addition of 0% fly ash + 0% steel slag is 4.07 MPa, 5% fly ash + 5% steel slag is 2.90 MPa, 5% fly ash + 8% steel slag is 3.43 MPa, 5% fly ash + 10% steel slag is 3.77 MPa, 5% fly ash + 12% steel slag is 4.20 MPa. Meanwhile, the concrete absorption rate with the addition of 0% fly ash + 0% steel slag was 2.13, 5% fly ash + 5% steel slag was 2.06, 5% fly ash + 8% steel slag was 2.12 MPa, 5% fly ash + 10% steel slag was 2.36, 5% fly ash + 12% steel slag was 2.57
