AB 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 solutionto recycle them. Among polymers, polyamide represents an important proportion of polymerwaste. In this study, sustainable and lightweight mortars were designed and elaborated, substitutingthe aggregates by polyamide powder waste. Mortars were produced with various dosages ofcement/aggregates, and the polyamide substitutions were 25, 50, 75, and 100% of the aggregates.The aim of this paper is to determine the density and the compressive strength of the manufacturedmortars to observe the feasibility for being employed as masonry or rendering and plastering mortars.Results showed that with increasing polymer substitution, lower densities were achieved, rangingfrom 1850 to 790 kg/m3in modified mortars. Mortars with densities below 1300 kg/m3 are catalogedas lightweight mortars. Furthermore, compressive strength also decreased with more polyamidesubstitution. Obtained values in recycled mortars were between 15.77 and 2.10 MPa, but the majorityof the values (eight out of 12) were over 5 MPa. Additionally, an economic evaluation was performed,and it was observed that the use of waste polyamide implies an important cost reduction, apart fromthe advantage of not having to manage this waste material. Consequently, not only the mechanicalproperties of the new recycled materials were verified as well as its economic viability.
