ABSTRACT:
The inventive cement-based composition is useful as a coating material for corrosion-resistant protection on steel and iron surfaces. The composition is basically a polymer cement composition prepared by compounding a hydraulic cement with an aqueous emulsion of a polymeric constituent but characteritically the inventive composition is prepared by adding an aqueous emulsion of a hydrocarbon solvent such as kerosene containing a combination of surface active agents, i.e. oil-soluble non-ionic, water-soluble non-ionic and water-soluble cationic ones, and a saccharide compound such as glucose. By virtue of the unique formulation, the composition has a greatly extended pot-life suitable for coating works of, for example, steel rods and pipes by the dip coating method.
