Keywords: concrete; controlled permeable formwork; performances; pore structure 1. Introduction The ingress of chloride is a principle cause for reinforcement corrosion in concrete elements. For attaining long-term durability, the improvement of impermeability is essential for concrete structures[1-3]. It can be achieved by increasing cement content for entire volume of concrete and reducing ...

01/02/2013  Controlled permeability formwork (CPF) is a kind of non-woven formwork, which is a widely used product in the spinning industry. In this paper, the effect of CPF on the water adsorption property of concrete was studied. Surface appearance, meso-surface morphology and microstructures of concrete blocks were characterized to analyze the affecting mechanism of CPF on concrete

01/02/1991  Controlled permeability formwork (CPF) can increase concrete durability in the critical cover zone, improve surface appearance, and reduce formwork pressures. The system is comprised of a filter, drain, and structural support. While the concrete is being compacted, air and some of the mix water escape through the form leaving the concrete in the cover zone with a reduced water-cement ratio
