Différentes approches pour la formulation des bétons autoplaçants
No general method is available in France to optimise SCC composition, and therefore design requires a lot of trials in laboratory or in most of cases directly in plant. However more rational approaches can be found in recent publications. The aim of this paper is to compare three of the most recurrent methods. The first one is a very simple mix design: coarse and fine aggregates contents have fixed values, and superplasticizer and water proportions are determined by mortar tests. The second method proposes two criteria to minimise paste volume. The third approach is based on the packing and on several models describing the properties of the fresh SCC. According to the French Standard P18-305, different SCC have been designed, without viscosity agents, by these methods, and their properties at the fresh state have been characterised with tests advised by the AFGC The experimental results provide new solutions for SCC designers in an industrial context. A study of the effect of mix design on harden state properties is provided too.
