A method of reducing corrosion in tubular strings installed in wellbores includes dispensing an accelerated cement composition into a wellbore annulus, a casing-casing annulus, or both, the accelerated cement composition comprising a cement composition and an accelerant composition, where: the cement composition comprises a cement precursor and water; the accelerant composition comprises triethanolamine; and a concentration of the triethanolamine in the accelerated cement composition is greater than or equal to 10,000 parts per million by weight; allowing the accelerated cement composition to cure in the annulus to form a cured cement, where the triethanolamine reacts with a metal of the tubular string, the reaction forming a protective layer on the surfaces of the tubular string that inhibits dissolution of iron from the metal of the tubular string.

This invention encompasses asphalt cement emulsions, as well as methods for preparing a pre-treated rubber-modified asphalt cement emulsions and methods for coating industrial surfaces using asphalt cement emulsions.

The invention relates to a composition for making flooring material comprising resin and particles comprising ammonium quaternary salt. The resin is generally an unsaturated polyester resin. The flooring materials, or engineered stone slabs from which the flooring materials or other material can be formed, are generally made from combining the resin, particles, inorganic particulate material and an initiator and allowing the resin to cure. The flooring material composition may be cobalt free. Metal catalysts may be used to cure the resin.
