Abstract
In this research, 210 concrete cube specimens (15cm) were made replacing 0, 5, 10, 15, 20, 25, 30, 35, 40, 50, and 60 percent of slag powder from Isfahan Steel Mill for cement. The control specimens were made with 350 kg/m3 cement content and the water cement ratio in all specimens was 0.51. The Slump value and compressive strength of concrete specimens in 7, 28 and 90 days were obtained and the results were compared. The test results show that replacement of 25 to 35 percent or slag powder for cement gives satisfactory results in obtaining concrete with suitable compressive strength and slump value. Also the results indicate that by increasing the percentage of slag powder replaced for cement, the shrinkage of the concrete and its resistance against sulphates will increase.
