Analysis and Economic Evaluation of the Use of Recycled Polyamide Powder in Masonry Mortars

Due to the considerable amount of waste plastics and polymers that are produced annually, the introduction of these waste products in construction materials is becoming a recurrent solution to recycle them. Among polymers, polyamide represents an important proportion of polymer waste. In this study,...
