| Abstract. | Low level of chemicalixation of building of Russia in comparison with the developed capitalist countries, the severe shortage and dearness of multifunctional modifying additives and fillers for building materials, solutions and concrete define a problem of search and working out of new effective modifiers as one of the major problems of increase of building manufacture efficiency. Scientific interest is represented by a liquid waste from manufacture of antibiotics. By results of the chemical analysis it is possible to draw a conclusion that waste can be attributed to groups to surface-active substances (SAS). Isotherms of adsorption represent the typical combined systems consisting of several (SAS). Here peptides, lipids, proteins, purine acid at which molecules are present both unpolar hydrocarbonic chains and polar groupings concern (СООН, -ОН, -NH). |
