Multi-parametric characterization of a sustainable lightweight concrete containing polymers derived from electric wires

The present paper reports the results of the experimental investigation of a sustainable lightweight concrete containing polymers derived from the recycling of the sheets of electric wires. After the removal of the copper, the plastic insulating sheet is ground into small size granules. Firstly the chemical and physical properties of plastic granules are investigated and their applicability in concrete is studied. Measurements of dynamic stiffness, impact sound pressure reduction and thermal conductivity show that the developed concrete can be successfully used for thermal and acoustic insulating lightweight screeds to be applied above the concrete structural slabs in floors.
