Abstract:
A self-compacting concrete (SCC), which is usual in local precast, was used as reference. The variables analysed were the type of fibres and their amount. Properties of concretes in fresh and hardened state were studied. The use of fibres, compared to the SCC without fibres, significantly influences the rheology in the fresh state and improves mechanical resistance in the hardened state. As regards the air permeability and the resistance to chloride penetration, the results obtained do not differ significantly between the two states.
