This thesis deals with the study of the influence of the water variations in the concrete-formwork interface. The proposed approach is intended to analyze two aspects. • The role of the concrete mixing formulation, and the casting procedures on the finished mortar surface. • The movement of water in concrete formwork interface. Firstly, we search to confirm the phenomenological results on the relationship between the luminance of the concrete surface and its roughness, this last being governed by the local W/C ratio in the formwork interface. This relationship will be established for compositions of modern concrete. After, we will examine the role of operational factors on the granular segregation on the mortar surface and their consequence...
