The article proposes the creation of optimized synergistic structures between additive materials, from the category of industrial by-products, through experimental modeling, which will ensure the increase in the performance level of the final products, in accordance with the needs and capacities of the materials market in the field of constructions and climate change. The experimental applications based on the integration of industrial by-products, allowed the definition of multi-criteria requirements necessary to improve the technical and environmental performance characteristics of materials and methods of engineering works. The improvement of the technical and environmental performance characteristics of the newly designed structures will allow the approach and implementation of alternative solutions for the valorization of industrial by-products, with the extension of the life span and reproduction in the economic circuit, as well as the reduction of the negative effects associated with the massive production of materials used in the field the constructions.
