Design of a methodology for the elaboration of ecological bricks incorporating low-density polyethylene

Abstract

Low-density polyethylene (LDPE) is generally found in the form of bags that are used to pack or transport merchandise; however, the proper disposal of this non-biodegradable material has been a great challenge, since, worldwide, it is calculated that only 9%, of the 9 billion tons that have been produced so far, has been recycled. In Mexico, it is estimated that 8 million tons of this material will be generated annually and only 14% will be recycled. On the other hand, the recycling of these residues, as an aggregate in construction materials, is considered an environmentally sustainable application. The objective of this article is to develop a methodology for the design of ecological concrete bricks incorporating LDPE from design as part of its aggregates, which will be obtained from articles with results presented, thus seeking to analyze the best design; this as an alternative to bricks commonly found in the construction industry. Although bricks made only with LDPE and sand have given good results, in relation to the use of plastic in intervals of 25 to 50%, it is expected that by adding Portland cement, they will have better physical and mechanical properties.
