Incorporation of fine plastic aggregates in rendering mortars

Highlights Two types of plastic recycled aggregates up to 15% of sand volume in rendering mortars. Some properties declined: mechanical and adhesive strength, water absorption. Improvement in water vapour permeability, impact resistance and dimensional stability. The shape and number of recycled particles are relevant and need to be considered.
Abstract The increasing growth of plastic in our Society has triggered the search for methods to solve the industry’s waste disposal. The interest of recycling this material, both in ecologic and economical terms, is not only due to its aggressiveness towards the environment but also to its high volume of landfilled material along with the fact that it is non-biodegradable. This paper approaches these issues within the context of sustainable development, considering a new application for plastic waste and studying the effects of its incorporation in mortars. Three substitution ratios of recycled plastic for natural aggregate have been considered, 5%, 10% and 15%. This substitution was made in volume and only in the 1–2mm fraction. This research also studied two types of PET aggregates, PP and PF aggregates that stand for plastic pellets and plastic flakes. The results show that, although the incorporation of plastic aggregates led to a worse performance in some properties, in others the modified mortars revealed a significantly improved performance in comparison with the control mortar (without plastic).
