摘要

Mortars and concretes are formulated from hydraulic binders, and are adapted for more rapid setting and hardening in cold weather, such formulations including the admixture of hydraulic binder, aggregates and water, and such formulations being characterized in that they include: (a) a water-soluble dispersant/water-reducing agent; (b) an inorganic basic agent selected from the group comprising the hydroxides of alkali metals other than lithium, alkaline earth metal hydroxides and the mixtures of one of such hydroxides with lithium hydroxide; and (c) a water-soluble salt of an inorganic oxyacid or an aliphatic or aromatic carboxylic acid, said acid having an ionization constant pKa of less than 2.5 in water at 25 DEG C.
