Hydration reactions and stages of clinker composed mainly of stoichiometric ye'elimite

Mohsen Ben Haha, Karen Scrivener, Emmanuelle Boehm Courjault, Frank Bullerjahn

Ye'climitc (Ca4Al6O12SO4 or C(4)A(3)(S) over bar) is the main hydraulic mineral present in calcium sulfoaluminate cement (CSA). The hydration of ye'elimite is responsible for the early age cement properties. We identify 5 stages in the hydration of neat st ...

Factors influencing the hydration kinetics of ye'elimite; effect of mayenite

Mohsen Ben Haha, Karen Scrivener, Frank Bullerjahn

The aim of this study was to understand the origin of the variation in the hydraulic reactivity of ye'elimite systems. To this end, the hydration of two clinkers, one composed mainly of synthetic stoichiometric (C(4)A(3)(S) over bar) "Y" and the other of a ...

Chemical shrinkage of ye'elimite with and without gypsum addition

Mohsen Ben Haha, Karen Scrivener, Frank Bullerjahn

Ye'elimite (Ca4Al6O12SO4 or C(4)A(3)S) is the main hydraulic mineral present in calcium sulphoaluminate cement (CSA). Its reaction is responsible for the (early) hydration and associated cement properties such as the chemical shrinkage. This paper discusse ...

Characterisation and hydration of ye'elimite containing cements

Frank Bullerjahn

Calcium sulphoaluminate cements (CSA) with the main phase yeâ elimite are a promising class of non-Portland cements which are gaining increasing interest from the cement industry. However, the hydration kinetics of CSA cements varies strongly, even for ce ...
