Uma visão geral sobre argamassa autonivelante e a potencialidade da adição de fibra polimérica reciclada

Abstract

The self-levelling mortar, also called self-compacting mortar, is an alternative that is very practical for the execution of subfloors, as the consolidation procedure, whether by vibration or manual compaction, is unnecessary. Its emergence contributed to the modernization of construction systems, increasing productivity and optimizing time at construction sites, as it is a material with easy and quick application that is increasingly present in the civil construction sector. The high fluidity is the main characteristic that makes the self-levelling mortar a special material, giving it the ability to fill molds and different shapes through its own weight, due to its high flow power, so that it does not need any type of compaction energy, in addition to helping to reduce possible imperfections in floors. However, the emergence of reports of pathological manifestations, such as, for example, cracking, influenced the beginning of numerous researches aimed at the use of fibers from the recycling of PET bottles (polyethylene terephthalate) as an addition to self-levelling mortars. In addition, PET bottle fibers contribute to reducing the environmental impacts caused by civil construction to the environment. This work aims to present and analyze research on the use of PET bottle fibers in mortars and raise the potential of adding PET bottle fibers to self-levelling mortar.
