Abstract (EN): The work presented in this paper aims at contributing to sustainable construction through enhancement of durability of concrete structures. Full size precast elements were cast with both self-compacting concrete (SCC) and conventional vibrated concrete (CC) using controlled permeability formwork (CPF). SCC is known to impart a more homogeneous and finer microstructure, compared to conventional concrete, therefore leading to more durable reinforced and pre-stressed concrete structures. CPF enables, in fresh concrete, drainage of excess water and air besides retaining binder particles at the concrete surface, leading to a blow-hole free surface and enhanced quality of the outer layers. The research program developed was designed to compare performance of two different CPF systems and also assess the combined effect of using OF on SCC compared to CC.
