Plastics have found uses in various applications. Their widespread use results in enormous amounts of waste which must be properly recycled or recovered. One possibility is the recycling of plastic waste and its use in concrete. As a part of my Master's thesis, we carried out our research on waste plastics such as PE, PP and PVC. In the first part of it, we reviewed the current research on the use of plastics in concrete. This was followed by plastic waste characterization in order to make concrete recipes. In the final part of our research, we partially replaced natural aggregate in concrete with waste plastics and subjected it to standard laboratory tests.
