<p>Said adjuvant comprises whole animal blood and/or cruor serving as an air-entraining agent proper, and is characterized in that it comprises in addition blood plasma, as an agent for stabilizing the entrained air, preferably in a powdered or atomized form. The proportion of blood plasma in the adjuvant represents advantageously between 15 % and 25 % by weight. It also contains dispersion products of the bentonite and/or alumino-magnesium clay types. In this way an adjuvant is obtained which has an exceptional air entraining capacity with a high stability, and which is easy to use because any type of mixer can be employed.</p> |
