Özet

The properties of reactive powder concrete with different plastic fiber ratios were investigated at different temperatures. Samples with the dimensions 7 x 7 x 7 cm were produced using CEM I 52.5 R cement, quartz sand, quartz powder, silica fume, steel wire, a superplasticizer, polypropylene fibers, and water. To achieve high strength the concrete specimens were subjected to compression after casting and accelerated curing. After the curing process, the concrete was exposed to temperatures of 20, 100, 400, 700, and 900 degrees C for 3 h. A cooling regime was slowly applied to the air after the heating process. Compressive strength, unit weight, and ultrasonic pulse velocity tests were performed on the samples. The physical structures and compressive strengths of the samples were examined.
