These special materials transform concrete from a purely structural element into a means of esthetic expression. Colored pigments allow concrete to be customized in a variety of colour palettes, moving away from grey tones, while decorative stones add textural richness and visual variety to the surface. The use of chemical solutions to remove the surface of concrete to reveal aggregates is called ’etching’ or ’surfacing’. The ’Non-Corrosive Concrete Surface Abrasive Solution, developed in collaboration with industry and academia and registered with the Turkish Patent Institute under application number 2023/019603, reacts with alkaline cement to neutralize the top layer of the concrete surface and properly expose the sand/aggregate matrix beneath the concrete shell. The domestic and national chemical product developed because of this collaboration is one of the priority products published by the General Directorate for Strategic Research and Productivity of the Ministry of Industry and Technology. The solution was optimized with the support of the KOSGEB R&D and Innovation Project, and preliminary trials of the solution have been successfully completed. Companies producing GFRCs, which use specialty chemicals imported from abroad, have ended their foreign dependence on this domestic product. Our country’s ability to produce solutions based on its own resources has been strengthened, and an important step has been taken towards a sustainable future in the GFRC sector. Owing to the corrosion inhibitors contained in the product, the corrosion of the steel-frame elements used in the assembly of GFRC facade elements is prevented, which is the most important innovation in this field.}, number={1}, publisher={Bayburt Üniversitesi}
