Title (EN) USE OF FERMENTATION RESIDUES AS FLOW-ENHANCING AGENTS IN CEMENTITIOUS MATERIALS
(FR) UTILISATION DE RESIDUS DE FERMENTATION EN TANT QU'AGENTS FLUIDIFIANTS POUR MATERIAUX A BASE DE CIMENT
Abstract: front page image
(EN)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.
(FR)L'invention porte sur un adjuvant pour ciment, panneaux de plâtre, et autre produits analogues, dérivant de résidus de distillation, comprenant normalement des protéines, du glycérol, et un lactate, ainsi que des doses plus petites d'alcools, de sucres et d'autres acides organiques, et pouvant se présenter sous forme de solution (comprenant normalement environ de 30 à 50 % en poids de solides), ou sous forme de mélange sec. Ledit adjuvant accroît la fluidité et réduit l'apport en eau des mortiers de ciment, et des coulis de plâtre utilisés dans la fabrication de panneaux de plâtre. L'invention porte également sur des prémélanges de béton, de ciment et de plâtre et sur des éléments préfabriqués coulés
