Abstract

Cement is made water-repellent during storage by the addition immediately before, during or after the grinding stage of its manufacteur, of a minor proportion of the order of 0,25% by weight of an additive consisting of a fatty acid or a mixture of a fatty acid and commercial cetyl alcohol, e.g. stearine in powdered or liquid form, or a mixture of stearine or whale acid oil with 2 to 20% of commercial cetyl alcohol.
