The aim of this work is to study the thermo-physical parameters of a mixture based on concrete and polyethylene terephthalate (PET). The two materials are mixed in a defined mass ratio to produce a new material, whose thermo-physical parameters (thermal conductivity, thermal capacity) are determined using a CT-meter apparatus [1]. The measuring cell is a temperature-controlled glove box. The experimental results show an improvement of the thermal performance while adding plastic waste. The conductivity and the thermal capacity of the composite decrease as a result of the addition of recycled plastic.
