The addition of steel fibers leads to an improvement in ductility and tenacity of the concrete, making it advantageous for many applications. However, it causes a reduction in the mixture workability, and that is why superplasticizer additives are usually incorporated in fiber reinforced concretes, which may give them a fluid consistency. To ensure the cohesion of a fluid mixture, there must be a higher content of fines in the mixture. In this research and paying attention to the concept of eco-efficiency, was achieved with the addition of marble and granite residues. This study aimed to apply a fibrous fluid eco-efficient concrete in the precast industry, performing a comparison with the production made in the laboratory. We can conclude that the application in precast factories is feasible, increasing the final quality of the parts and promoting improvements in the production process itself. However, we identify some difficulties in its implementation.

Palabras llave : Fibrous fluid concrete; precast concrete; marble and granite residue; ecoefficient concrete.
