The addition to concrete of fibres in low to moderate contents in volume (0.5%-1%) enhances ductility and fracture energy, but has little influence on resistance. Therefore, conventional reinforcement cannot be replaced by fibres, although more efficient crack control can be achieved: the combined action of rebars and fibres leads to smaller crack spacing, improved tension stiffening and hence to smaller crack widths. In this paper an ongoing research on crack width control enhancement with steel fibres recycled from used car tires is presented. Experimental results are compared with analytical predictions, in order to help develop a model for crack width prediction. The main objective of this investigation is the evaluation of the efficiency of a new type of fibre technology in integral (jointless) structures, with advantages from the point of view of sustainability due to the use of recycled fibres in low amounts. | |
