The present invention provides substantially water free aluminate cement paste compositions that exhibit improved freeze thaw resistance and are storage stable upon being activated on admixture with water or an aqueous liquid. The compositions comprise a deep eutectic solvent mixture of a polar organic carrier component, preferably, glycerol or another hydrogen donor, and an anhydrous cation containing component, such as a metal salt or an onium compound in a paste with an aluminate cement. The compositions can be kept for as long as 30 days or more at room temperature without stabilization and then used to make cementitious coating layers or waterproofing membranes.
