Effective Concrete Modified by Complex Additive Based on Waste Products of Construction Acrylic Paints

摘要

Improvement in quality of concrete compositions can be achieved both by using chemical additives, and using local components to create a new generation of concrete, which is a highly relevant objective for concrete technology. The industrial wastes produced by the enterprises of Volgograd region are complex mineral and organic compounds having various chemical and physical properties. Among additives of the organic nature the construction acrylic paints production waste is of scientific and practical interest. It has been checked that it is possible to use an organic additive, a water-dispersible acrylic monomer (WDAM)-construction acrylic paints production waste as a modification, in the fine grain concrete, improving the basic properties of the construction composition. Studies have shown particular pattern of the modified concrete formation process, consisting of the water-repellent plasticizing effect of WDAM additives. The regularities of changes in the quality parameters of the concrete composition and the number of introduced additives are established. The relations of changing performance properties of effective concrete with modification WDAM have been confirmed by the results of experimental studies and developed regression model. The study shows that the creation and use of new modifiers is one of the actual ways to further enhance the performance of building materials, as well as evidentiates the tendency to expand the list of chemical additives with complex effect with organic waste. It is evident that the utilization of waste products and more efficient use of material resources have a proven economic effect.
