Abstract
Herein is disclosed an admixture, for concrete, gypsum panels, and other cementitious products, derived from fermentation still bottoms. The admixture typically comprises protein, glycerol, and lactate, as well as smaller amounts of other alcohols, sugars, and other organic acids. The admixture may be present as a solution (typically comprising about 30-50 wt % solids) or as a dry mixture. The admixture allows increased flow and reduced water use in concrete and gypsum slurries used in gypsum panel production. Concrete, cement, and gypsum premixes, ready-mixes, and poured structures are disclosed.
