One of the major disadvantages of the domestic industry is its high resource intensity, due, among other things, to the low level of use of secondary raw materials. There are a lot of problems associated with the disposal of polymer waste. They have their own specifics, but they cannot be considered insoluble. One of the methods of recycling is the use of plastic waste as aggregate in cement mortar and concrete preparation. The article contains and analyzes the methods, physical properties of concrete, with plastic aggregate and physical properties related to the operation, durability of concrete containing plastic aggregates. Based on the results of the review, it was concluded that the technique of using plastics in cement mortar and concrete preparation is effective and cost-effective. The results suggest that the use of recycled plastic fibers and pellets in concrete can lead to improved concrete properties. The article considers the physical properties associated with the operation and durability of concrete containing plastic aggregates and fibers, types of plastics and cement, the chemical composition of the cement used in the study, the main joints, shrinkage, compression strength, bending strength, modulus of elasticity, water adhesion and porosity, thermal conductivity, fire resistance. The use of recycled plastic aggregates and fibres as a building material is attracting increasing attention.
