The disposal of post-consumption tires and plastics has become a significant environmental concern. New routes for recycling and using polymeric waste are needed since current treatment and disposal options do not reach the production of these materials. In this context, this study aimed to evaluate the effect of the use of tire and polyethylene terephthalate (PET) waste at different amounts on the physical, mechanical, thermal, and durability properties of extruded fiber-cement. Portland cement was replaced with 1, 2, 3, 4, and 5% by weight of polymeric waste from tire and PET. The fiber-cement was evaluated at 28 curing days and after accelerated aging, for density, water absorption, porosity, modulus of rupture, modulus of elasticity, proportionality limit, tenacity, and thermal conductivity properties. Tire and PET waste could be used as reinforcement material in fiber-cement, allowing for not only the correct destination and development of more sustainable new products but also the improvement of physical, mechanical, thermal, and durability properties of extruded fiber-cement.
