Description
Summary:In this paper, the possibilities of creating composite materials based on cross-linked polyethylene (XPE) were investigated. The environmental benefit of recycling such polyethylene is to free up space for buildings that are now occupied by landfills. The influence of polyethylene, previously considered non-recyclable, on the strength characteristics of concrete is shown. In the course of the work, waste from the existing chemical industry was used, with varying particle sizes (0.5-15 mm). The analysis of patent information on the utilization of polyethylene in construction materials. Using mathematical planning methods, the compositions of composite materials are optimized. The volume of solid waste of non-recyclable plastic is more than 1.3 billion tons. Its decay period in the natural environment is more than 400 years. There is no world experience in the use of such waste, so the problem of its disposal is more than relevant. Thanks to the results obtained, it is possible to significantly reduce the degree of environmental pollution by waste of chemically cross-linked polyethylene, and get a new composite material for construction, a wide range of applications. The economic justification of the developed technology being introduced into mass production is presented.
