Minerals of expansive and non-shrinkage sulfomineral cements
MATEC Web of Conferences, 2017 Usually to obtain expansive cements sulfoaluminate clinker or mix aluminate clinker with calcium sulfates (gypsum, hemihydrate, anhydrate) are used. For these cements ettringite is an important hydration product and kinetic reaction of this phase plays ...
