Descrição

This paper reports on the work that is being undertaken at the University of Minho concerning the development of directionally oriented fibrous structures (DOFS) to be used as a concrete reinforcement material. Several glass fibre wovenlike DOFS were produced varying two parameters: roving linear density (tex) and reinforcement structural density (rovings/cm). Self-compacting concrete slabs were reinforced by DOFS structures and their bending behaviour was evaluated. The results were compared with those of steel reinforced slabs and plain (non reinforced) concrete slabs. They show that DOFS improve the mechanical behaviour of self-compacting concrete, however, their mechanical behaviour is different from steel.
