Abstract
Buildings' performance building is in evidence in Brazil, especially after the adoption of the Performance Standard ABNT NBR 15575: 2013ASSOCIAÇÃO BRASILEIRA DE NORMAS TÉCNICAS. NBR 15575: edificações habitacionais: desempenho. Rio de Janeiro, 2013.. This standard is concerned with the need of building systems to meet minimal fire safety requirements, among others. The aim of this paper is to investigate the potential application vertical sealing of reinforced concrete for fire resistance purposes by the construction industry. Through prototypes tested at full scale (3.15 x 3.00 m) in a standardized vertical furnace, two wall thicknesses (10 and 14 cm), with the same concrete mix were analysed by observing their behaviour in terms of thermal insulation, sealing and stability. The tests demonstrated that the samples met the applicable conditions for up to 120 minutes of testing, with the 14 cm thickness showing better rates of thermal insulation and sealing.
