Abstract
Concrete is one of the most important construction materials, which, due to its properties, provides complete freedom in using it in construction, and thus in shaping the space. Despite numerous advantages (ease of use, high compressive strength, low production cost, resistance to high temperatures), it also has disadvantages, which include, first of all, low tensile strength and sensitivity to the destructive effects of chemical agents. The continuous increase in expectations regarding the improvement of concrete quality meant that concrete began to be modified, inter alia, with polymers to eliminate the above-mentioned disadvantages. This paper presents a review of articles on the possibilities of using polymer waste in concrete technology and their impact on the quality of the produced concrete composites.
