Abstract: A hydraulic cement mix comprising a hydraulic cement, aggregate in an amount of up to 80% by weight based upon the total weight of said cement mix, sufficient water to effect hydraulic setting of the cement, and an air-entraining additive consisting essentially of a coconut fatty acid diethanolamine produced by reacting alkyl ester of coconut acid with diethanolamine, a capramide diethanolamide and ricinoleic acid, said additive being in an effective amount whereby air will be entrained in said mix in an amount of 3% to 9% by volume of said mix.
