Optimisation of formwork stripping time in vertical self-compacting concrete parts

Abstract

The demoulding time is affected by the development of the concrete resistance, since the formwork will be removed once the concrete is able to support itself and the corresponding efforts of the striking. This work has focused on the experimental study of the methodology of demoulding described by Teixeira [1], and on the optimization of demoulding times through the study of the minimum resistance required for stripping vertical pieces.
