The present invention relates to an air-entraining adjuvant. This adjuvant comprises animal whole blood and/or cruor serving as the actual air-entraining agent, and also comprises blood plasma as a stabilizer for the entrained air, preferably in pulverulent or atomized form. The proportion of blood plasma in the adjuvant is advantageously from 15 to 25% by weight. The said adjuvant also contains dispersants of the bentonite type and/or aluminomagnesium clay type. This gives an adjuvant having an exceptional air-entraining capacity with a high stability; it is easy to work with as any type of mixer can be used. |
