Abstract
A process and composition of matter for the treatment of mortar or concrete which includes fly ash containing carbon, for the purpose of increasing air entrainment. A small quantity of a soluble alkaline earth oxide is added to the mortar or concrete at the time of mixing. The material is added in form which is immediately available to inhibit the air-adsorptive properties of the carbon in the fly ash.
