Özet

In this study, PC 52.5 CEM I R and blast furnace slag were used to prepare Slurry Infiltrated Fiber Concrete (SIFCON). While preparing the control mixture with 100% cement, the blast furnace slag in the other two series was replaced with cement by 25% and 50%. 5% of steel fiber was used in three prepared mixes. The series using 25% and 50% slag were also produced with a 10% fiber ratio. 7 and 28 days compressive and flexural strengths of 5 series were found. Besides, a freezing-thawing test (with 300 cycles) was applied to the samples. Compressive strength, weight loss, and flexural strength were found at the end of the freeze-thaw test. Besides, visual inspection was done after the freeze-thaw test. When the conclusions were investigated, it was observed that the slag decreased the early strength and created higher values in the 28-day results. It was seen that increasing the fiber ratio increased the strength values. SIFCON samples were found to be resistant to the freeze-thaw test.
