Abstract
Cement material, curable in the presence of water and including a hydraulic binder composition, which contains a mixture of hydraulic binders and a mixture of sulphate sources, wherein the hydraulic binder mixture includes: at least one hydraulic binder containing an alite-type mineralogical phase and at least one hydraulic binder containing an aluminate-type mineralogical phase, mainly consisting of ye'elimite (C4A3$) or a mixture of ye'elimite and calcium monoaluminate (CA), the mixture of sulphate sources containing at least one sulphate source with a solubility of <4 g·L−1, and at least one sulphate source with a solubility >4 g·L−1, the cement material optionally including mineral additions, fine granulates, large granulates and additives. The curable cement material is useful as a material capable of setting in cold weather, in particular a concrete, a mortar, a grout, a coating or a cement paste to be used at a temperature of −10° C. to +5° C.
