Abstract of the Disclosure The present invention relates to an epoxy resin- polyammonium salt emulsion composed of a liquid epoxy resin, a latent curing agent, an emulsifier, and water, wherein (a) the emulsifier is a primary aliphatic alcohol of 12-14 carbon atoms, the adduct thereof with up to 5 ethylene oxide groups, or a carboxylic acid polyglycol ester, and (b) the latent curing agent is the reaction product obtained by complete neutralization of an acid consisting of or containing oxalic acids with a polyamine of the formula H2N ? CH2 - CH2 - NH ? H wherein x = 2, 3, and 4 or with a reaction product which contains amino groups and is prepared by reacting the polyamine with fatty acids. The emulsions of the present invention are useful in epoxy resin mortars or epoxy resin cement mortars and for sealing concrete surfaces to improve the water retention capacity.
