Abstract
The bioadditive is used in the construction industry. It ensures optimal homogeneity for the mixture, while minimizing the use of cement and reducing the water content. It has a stabilizing effect on the cement, gypsum or limestone suspension. The additive represents an alkaline treated biomass containing, in percent: 3-15 dry matter, 50-80 proteins, 3-10 fats, the remainder salts. The method involves alkalising the biomass with 1.5-4.0 percent sodium or potassium hydroxide and heating the mass up to 50-80 degrees C for 1-3 hours until partial hydrolysis of the proteins is achieved.
