Use of fermentation residues as flow-enhancing agents in cementitious materials

   
   

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.

É divulgado nisto um admixture, para o concreto, os painéis do gypsum, e outros produtos cementitious, derivados dos fundos do fermentation ainda. O admixture compreende tipicamente a proteína, o glycerol, e o lactate, as.well.as quantidades menores de outros álcoois, os açúcares, e outros ácidos orgânicos. O admixture pode ser presente como uma solução (que compreende tipicamente % dos sólidos de aproximadamente 30-50 pesos) ou como uma mistura seca. O admixture permite o fluxo aumentado e o uso reduzido da água nas pastas do concreto e do gypsum usadas na produção do painel do gypsum. O concreto, cimento, e os premixes do gypsum, pronto-misturam, e as estruturas derramadas são divulgadas.
