摘要：

Controlled permeability formwork liner (CPF) is a novel approach for improving the concrete cover zone’s quality. This method is used to keep tiny cement and sand particles in place while removing excess water and trapped air from the surface of freshly laid concrete. The concrete’s surface zone consequently has a higher cement content, a lower surface porosity, and a lower water to cement ratio. CPF action produces a smooth and even surface and also free of pinholes, blow holes and other flaws. The quality of surface concrete can be increased by utilisation of CPF and destructive agencies won’t be able to find an easy way into the concrete to damage it. Even though this technology marginally raises the initial construction costs, the increased durability achieved through the use of a CPF system may result in lower structural life cycle costs. However, by use of CPF liner the service life of concrete is enhanced by 2.3-2.5 times compared with conventional concrete. This paper presents a review on the use of CPF to enhance the quality of the surface of concrete, principle of its function, types and cost implication. © 2024, Associated Cement Companies Ltd..
