Koenders, E.A.B. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2014-12-31 Abstract In this paper a performance-based method for the design of granular-paste mixtures will be proposed. Focus will be on the selection and proportioning of constituents to produce a mixture with a pre-defined shape holding ability. Shape holding ability of mixtures will be characterized by the shape preservation factor SPF. This SPF shows the ability of a mixture to preserve its shape after being demolded from a slump test. SPF is the ratio of the cross sectional area of a sample after and before demolding. By increasing the flowability of a mixture, the SPF decreases. In this study a mixture is first decomposed into aggregate, void paste and excess paste. Then a combination of the consistency of the paste and excess paste volume is determined for a required SPF. Finally, depending on the aggregate grading, the volumes of paste and aggregates in the system are determined.
