Mortars and screeds containing polymeric aggregates recycled from industrial waste and tyres

Abstract

Given the growing market demand for products containing recycled components dictated by European and national policies, the presented research aimed to replace part of the natural aggregates in construction mortars and screeds with recycled polymeric aggregates (RA): industrial technopolymers and ground tyre rubber (GTR). The strategy involved the substitution of aggregates, both in market products and in the design of standard mortars, first verifying the CE certification and then the achievable mechanical performance. The whole process has been discussed in the context of a circular approach, extended to the analysis of the aggregate production phase, highlighting factors that influence environmental and economic impacts.
