Özet
In the last decade, a number of investigations on fiber-reinforced self-compacting concretes (FRSCC) have been carried out, and the mechanical behaviour and durability characteristics of this type of concrete are now better understood. However, the way in which fiber type affects mechanical and durability properties of this special composite has not been studied as extensively. This paper investigates the effects of three types of fibers - steel (SF), polypropylene (PPF) and polyvinyl alcohol (PVA) - on the compressive and flexural strengths, toughness, water porosity and chloride ion permeability properties of FRSCC, which were designed to contain considerably higher amounts of fiber (1% by volume). In addition, a plain concrete without fiber was produced and used as a control. Test results showed that use of fiber increased the water porosity and chloride ion permeability of the concretes, irrespective of fiber type. Use of SF increased the compressive strength, mid-span deflection, flexural strength and toughness drastically; however, use of PPF worsened those properties compared to the plain concrete.
