Mortar compositions

Claim 1

An aqueous mortar composition having a viscosity in the range of 10,000 to 1,200,000 cps comprising a film-forming, room temperature cross-linkable polymer in the form of an emulsion, suspension, dispersion or partial solution, having substituents on the polymer chain selected from the group consisting of epoxy, hydroxy, methylol, carboxy, ester, α-olefin, isocyanate, methylol acrylamide, amino, N-methylol amide, internal double bond and combinations thereof, wherein said substituents are capable of reacting at room temperature to cross-link said polymer, a water-insoluble filler selected from the group consisting of glass, quartz, silica, limestone, barytes, wollastonite, mica, flint powder, kryolite, alumina trihydrate, talc, pyrophyllite, zinc oxide and mixtures thereof, and a cross-linking aid which is an acidic catalyst selected from the group consisting of inorganic and organic salts, organic acids, and amine acid-addition salts, said polymer comprising from 2% to 16% by weight, and said filler from 50% to 90% by weight of the total aqueous composition and wherein said composition is a non-hydraulic mortar.
