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.

What is disclosed is a cellulose-based product and a method for producing the aggregate admix product that includes the steps of thoroughly hydrating cellulose fibers, mixing clay and mineral particulates with a liquid to produce an emulsion, adding the emulsion to the hydrated cellulose fibers, and thoroughly impregnating the cellulose fibers with components from the emulsion and producing an aggregate admix product. The aggregate admix product is combined with cement and a liquid to create a cementitious product that can be directly sprayed onto building structures.
