Abstract

Fibre reinforced concrete is widely used in the pavement construction despite presenting some economic and environmental issues. To address these matters, the concept of functionally graded material (FGM) concept with materials that present changeable properties over its volume is adopted on concrete, generating functionally graded concrete (FGC). To understand these new composite materials more studies are needed. In this study, eight mixes of FGC concretes were produced to assess the effect of the recycled aggregate and different depths of the fibre reinforced layer on the flexural performance. Besides, a simplified sustainability analysis was performed to assess the goodness of these special concretes. The experimental results indicate that the FGC studied could be used in structural applications requiring lower loading capacity. The sustainability analysis indicates that a cut in the total volume of steel fibres and the use of recycled aggregates would enhance the benefits of the FGC.
