Investigestion on durability of steel and carbon fiber mortars to sulfate effect

In this study, durability of steel and carbon microfiber usage which are added to the cement composites as different dosages, to sulfate effects are researched.In the scope of this study, in different microfiber dosages and different fly ash adding ratios, totally 28 mortar mixes are prepared including control mixture. Creep diameter, flexure, compression after flexure and length measure experiments are applied on these mixtures. After the mortar samples are held during 28 and 150 days in water, 150 days in sulfate, flexural strength and compressive strength after flexure are determined. Toughness values of the samples including minimum and maximum microfiber volume, which are held during 150 days in water and 150 days in sulfate, for every ratios of fly ash adding, are determined. Besides, weekly length measures are taken for every different mortar mixtures. Sulfate effects are investigated on mortar samples prepared with different ratios of microfiber and fly ash.
