Recycling of waste paint in concrete mortar

Every year, millions of liters of latex paint go to waste around the world. Considering the similarities in the chemical composition of waste paint and polymeric additives, this study aiming to use waste paint in concrete has emerged. In this study, the adequacy of using waste paint as a chemical additive in concrete mortar is discussed. It is a study towards the development of new cementitious materials with a lower environmental impact, given the importance of sustainability as the main driver for future innovations. Except for the amount of waste paint, all materials were kept constant, and the effects of waste paint on the concrete mortar, the properties of hardened concrete, and fresh concrete, were investigated as a result of a number of experiments. As a result of the experiments, it was decided that the optimum amount of paint to be used in the experiment was 3% while improving the fresh concrete properties of the waste paint. It was concluded that not all types of paints could be used, and it was determined that solvent paints disrupted the structure of the concrete mortar and segregated it. It has been concluded that using waste paint as a material that will affect the negative properties of normal concrete positively while eliminating wastes for a more livable environment will affect the properties of concrete in low tension concretes, namely pavements and bridge coatings, in a good way.
