O uso do poliestireno expandido (eps) na construção civil

Abstract

The choice of the theme was motivated by the observation of the growth in the use of EPS in civil construction, not only in terms of volume, but also by the diversity of applications. This work aimed to establish a comprehensive overview of the use of EPS in construction, considering academic, normative and technical aspects, with market data and based on consolidated scientific knowledge. The results demonstrated that quantity and content of academic productions related to EPS use in construction increased in recent years, with a total of 28 works related to EPS use in construction being found. From a market perspective, expectations of annual growth of 4.72% until 2028 prove the growing demand for the material. The data also showed that civil construction is responsible for 44% EPS market generated revenue. The normative aspect regarding the use of EPS is still very limited, only 8 documents were found, 3 of which are technical standards from ABNT and 5 technical documents from PBQP-H / SINAT. The EPS LCA study allowed us to conclude that EPS is a material with a positive balance between its benefits and impacts, providing improvements in the thermal and acoustic characteristics of the elements to which they are applied. For maximizing its potential, it is essential to promote recycling, reuse and adequate waste management, requiring the creation of policies for disposal, reuse and recycling of material, in addition to continuing to invest in research and development to improve its applications and reduce impacts. environmental problems caused throughout its life cycle.
