TY - CONF AB - This paper presents the results of an ongoing research on the effect of different curing regimes on properties of Ultra high performance concrete (UHPC) containing recycled steel tire wires as micro steel fibers. Outstanding properties of UHPC as next generation of concrete make it a promising material for different structural applications. The effects of different curing conditions on the mechanical properties of UHPC have been investigated by many researchers. However, limited research works are available that investigates the effects of different curing regimes on transport properties of UHPC. At this paper, different regimes of water curing (WC), air curing (AC), accelerated water curing (AWC) and autoclave curing (AUC) are applied on UHPC specimens containing 2 percents of recycled steel fibers (by total volume). The compressive strength and flexural strength are measured as mechanical properties. Water absorption, sorptivity (rate of water absorption) and pulse velocity tests were investigated on UHPC specimens in various curing regimes as transport properties and durability indexes. Results show that recycled fibers can be successfully used in UHPC mixes to produce an affordable and eco-friendly material. It has been found that both of strength and transport properties of UHPC can be significantly affected by applying the accelerated curing methods. Lack of attention on choosing an appropriate curing condition can lead to a significant increase in water absorption and sorptivity of UHPC.
