Abstract

Highlights: Fibers bridge between cracks and prevent propagation of cracks. Fibers reduce the water permeability because of controlling the crack width. Fibers are helpful materials in extending the service life of concrete structures. Fibers have not considerable effects on compressive strength. Abstract: In recent years, the application of synthetic fibers in concrete industry has surged to take advantages of their impacts on mechanical properties like enhancing toughness and impact resistance, decreasing shrinkage and even benefits from replacing of thermal reinforcing bars and steel fibers with these fibers. Nonetheless, there is paucity of practical studies conducted on the durability aspects of using these types of fibers in concrete structures under stressor medium. This research aims to investigate the impacts of three synthetic fibers with different physical properties and variable volume percentages on water permeability under pressure, electrical resistivity, half-cell test and water absorption. Moreover compressive and flexural strengths are measured. Results manifest that poly-olefin macro fibers had the best short term durability performance among those three fibers have been tested.
