Análise do desempenho térmico de concretos convencionais, não convencionais e compósitos especiais – uma revisão

Abstract

The civil engineering sector has followed a growing demand for housing and, in parallel, an increase in construction systems and materials, which have been increasingly exploited.In order to meet the minimum requirements of thermal performance for buildings, it is necessary that these systems and materials comply with the specifications of ABNT NBR 15575: 2013 - Performance of residential buildings.The present work aims to present a bibliographic review that covers in a diversified way the use of concrete in its different methods of application and mixtures, demonstrating the results regarding its thermal performance. In the first topic are the works that studied conventional concrete in conventional masonry systems and concrete walls cast-in-place. In the second topic, works focusing on sustainability, presenting results of studies using EPS, marble and granite waste and rice husks and straw mixed with concrete. In the third topic are studies focusing on unconventional materials, seeking to verify the thermal performance in “Light Steel Framing” buildings, one with closure in Novogesso and the other with closure in plasterboard and cementitious slabs. The results of these works were shown to be satisfactory in most cases, concluding that both conventional concrete, as well as concrete with alternative materials and unconventional concrete can be combined with the good thermal performance of buildings.
