    摘要: An additive for imparting water repellancy to, and retarding the set of hydraulic cement compositions (e.g. Portland cement compositions such as masonry cements) is described which is an aqueous oil-in-water emulsion containing water, a waterinsoluble, water-repelling acid component (e.g. tall oil), an emulsifier (e.g. a salt of such acid), and a setting timeretarding agent (e.g. sucrose). The additive is ideally dispersible in water and preferably contains an air-entraining agent as an additional optional component. Intergrinding the emulsified additive with the cement component is the preferred manner of incorporating the additive in the cement composition.
