Análise mecânica, térmica e acústica de argamassas com substituição do agregado fino por argila expandida. 2021. 57f. Dissertação (Mestrado em Engenharia Civil) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2021.https://repositorio.ufrn.br/handle/123456789/43727In the Civil Construction scenario, the mechanical, thermal and acoustic performance of buildings is a relevant theme for scientific research, especially after the publication of ABNT NBR 15575:2013, which brings together criteria and requirements regarding the performance of residential buildings. Under this bias, the objective of the work was to analyze the mechanical, thermal and acoustic behavior of lining mortars, using different contents – 10%, 20%, 30%, 40% and 50% – of a fine fraction of expanded clay such as partial replacement of the conventional aggregate. To carry out the work, important mechanical properties of the mortars were determined, both in the fresh state and in the hardened state. In terms of the thermal behavior of mortars, their thermal conductivities were analyzed. In addition, prisms were made to simulate the masonry sealing of buildings, in order to verify the thermal and acoustic insulation of the mortars under study, with the aid of incidence simulators and heat and noise transfer in the samples. The results show that the mortars incorporating expanded clay did not present negative impacts on their mechanical properties and with regard to sound insulation. Furthermore, it was observed that the increase in the expanded clay content in the composition of the mixes reduced the thermal conductivity by up to 34.1% and increased the thermal insulation potential by up to 15.9%, when compared to the mix without the incorporation of expanded clay with the dash with the greatest amount of this aggregate. Thus, the influence of light aggregate on the thermal behavior of the mortars under study is evident, without compromising their mechanical and acoustic behavior.Acesso AbertoConforto térmicoIsolamento acústicoArgamassa levemasterThesis
