Compósito à base de polipropileno reciclado para utilização nas construções rural e civil.

Abstract

The present study aims to carry out an analysis on the physical and mechanical properties of blocks composed of sand or stone powder agglutinated by recycled polypropylene through thermal treatment aiming the implantation for masonry and/or pavements in the civil and rural construction. With the main objective of replacing water and cement in the mixture and promoting studies on the composite using such polymer as an optimizer for future applications in favor of high resistance, the research was developed based on its own methodology involving the tests of resistance to axial compression, tensile strength by diametrical compression (brazilian test), water absorption by immersion and water absorption by capillarity in which different compositions of recycled polymers and compaction loads for modification of the composite were tested for better characterization. Comparing and observing improvements in the properties of the mixture, it was found that the increase in the addition of polypropylene in the mixture resulted in greater strengths and lower absorptions in the composite, enabling its use in civil and rural construction.
