Abstract: Additives for use as grinding aids and set retarders in the manufacture of hydraulic cement composed of polyglycerol, preferably a polyglycerol selected from the group of di-, tri-, and tetraglycerol and mixtures thereof, the additive being used either alone or in combination with at least one of a water-soluble glycol, a water-soluble hydroxy-alkyl amine, a water-soluble salt of a sulfonated lignin and a water-soluble salt of an aliphatic acid having no more than three carbon atoms, the hydraulic cement product of this addition and the method for making the cement product.

Abstract: There is disclosed herein oil-in-water anionic bituminous emulsions which comprise from about 30% to about 75% by weight of the emulsion of bitumen as the dispersed phase, and from about 0.1% to about 10.0% by weight of an anionic emulsifier consisting of an alkali metal salt of an alkali lignin, an ethylene oxide adduct of phenol, and water in an amount to make up 100% by weight as the continuous phase. Additionally, improved pumping times are obtained with the addition of from 1% to about 10% by weight of sodium borate.

Abstract: A process for making a wetting-dispersing agent whereby an aqueous mixture of a sulfonated lignin dispersing agent and an anionic or nonionic wetting agent in a weight ratio of dispersing agent to wetting agent of from about 19:1 to 1:3 are dried together to form a single product for use as a surfactant in pesticide formulations.

Abstract: There is disclosed herein oil-in-water anionic bituminous emulsions which comprise from about 30% to about 75% by weight of the emulsion of bitumen as the dispersed phase, and from about 0.1% to about 10.0% by weight of an anionic emulsifier consisting of an oxygenated alkali lignin, an ethylene oxide adduct of phenol, and 0% to about 10% by weight of sodium borate and water in an amount to make up 100% by weight as the continuous phase.
