Abstract

The world production of thermoplastic resins in 2016 was 407 million tons per year, of which 6.4 were produced in Brazil. From 1950 to 2015, 8,300 million tons were produced on the planet and 6300 million tons were disposed of without recycling. Brazil recycles on average 25% of this material. This research proposes the use of recycled polypropylene agglutinated as a substitute of the large aggregates in the concrete and, to this end, studies its behavior characterizing it by means of a composite based on Portland cement of high initial resistance, CP-V-ARI. The agglutinated polypropylene grains of this study were collected from the disposal in the industrial production line of plastic artifacts and are the result of adjustments and losses during the manufacturing stages, being thus waste without passing through any public collection system or selective collection program. The initial results concerning the axial, diametral and modulus tensile strengths of different strengths confirm the applicability of this composite in the production of prefabricated parts or components for civil construction.
