Use of raw plant materials for obtaining effective organic modificators of corrosion-resistant building binders on the example of gypsum plaster

The article presents the results of an experiment performed on the extraction of substances from raw plant materials (stems and leaves of reeds, stems and leaves of cotton, sawdust of poplar) and on the changes in the properties of gypsum plaster, a corrosion-resistant building binder after adding the obtained extracts to its composition. To obtain the extracts, aqueous, alkaline and acidic solutions have been used. The aim of the research is to prove the efficiency of using substances obtained as a result of their extraction from raw plant materials as corrosion modifiers of corrosion-resistant building binders. The objectives of the research are to assess the main indicators of the extraction of substances for the production of modifiers using raw plant materials in order to identify the most effective ones; to assess the properties of gypsum plaster without and with the extracts obtained from cotton stems and leaves, reed stems and leaves, and poplar sawdust. As a result of the experiment performed, on the basis of the obtained results, the effectiveness of using the extracts as modifiers of the organic type for improving the properties of binders using the example of gypsum plaster has been proved. Speaking of the use of modifiers in practice, they have a wide range of applications in the future and can be used in the production of dry-type construction mixtures, since they provide a number of properties in accordance with the requirements of the construction technology, depending on the quantitative content.
