A substantial growth in the consumption of plastic is observed all over the world in recent years, which
has led to huge quantities of plastic-related waste. Recycling of plastic waste to produce new materials
like concrete or mortar appears as one of the best solution for disposing of plastic waste, due to its economic
and ecological advantages. Several works have been performed or are under way to evaluate the
properties of cement-composites containing various types of plastic waste as aggregate, filler or fibre.
This paper presents a review on the recycling plastic waste as aggregate in cement mortar and concrete
productions.
For better presentation, the paper is divided into four different sections along with introduction and
conclusion sections. In the first section, types of plastics and types of methods used to prepare plastic
aggregate as well as the methods of evaluation of various properties of aggregate and concrete were
briefly discussed. In the next two sections, the properties of plastic aggregates and the various fresh
and hardened concrete properties of cement mortar and concrete in presence of plastic aggregate are
discussed. The fourth section focus on the practical implications of the use of plastic waste in concrete
production and future research needs.
