Tratamento de umidade ascensional em paredes através de inserção de barreiras químicas por gravidade / Treatment of rising damp in walls through chemical barriers by gravity

Socoloski, Rafaela Falcão January 2015 (has links)
A umidade nas edificações pode ser proveniente de diversas fontes. Entre elas está a umidade ascensional, que provém do solo na ausência ou falha de barreiras. A umidade ascende pelas paredes por capilaridade existente devida a estrutura porosa dos materiais de construção. Sua ação pode prejudicar o desempenho das paredes das edificações, possibilitando a degradação progressiva das paredes. Dessa forma, estas podem deixar de cumprir funções, como por exemplo, de proteção e acabamento. Vários tratamentos têm sido estudados pelo mundo. Entretanto a avaliação dos métodos de reparação das paredes afetadas tem sido um problema de difícil resolução. O objetivo deste trabalho é a avaliação da eficiência do tratamento de paredes com umidade ascensional através do método de corte hídrico por inserção do cristalizante através da ação gravitacional, utilizando os diferentes produtos disponíveis no mercado nacional brasileiro. Apesar de limitada a paredes pouco espessas, essa técnica tem apresentado eficácia, versatilidade de execução e baixa interferência na fachada da parede. Essas características justificam a escolha dessa técnica para servir de objeto de estudo do presente trabalho. Visto que não há ensaio normalizado para avaliar a eficiência dos produtos para tratamento contra umidade ascensional será utilizado como referência um experimento realizado por outros pesquisadores, explanado neste documento. A avaliação da umidade presente no corpo de prova é através da medição da massa e imagens com câmera termográfica. Constatou-se que, no período analisado, não houve a redução total da umidade ascensional, no entanto os cristalizantes conseguiram diminuir consideravelmente (em média mais que 50%) a absorção da água por capilaridade. / Dampness in buildings can be derived from several sources. Among them is the upward moisture, which comes from the soil in absence of barriers. The moisture ascends on the walls due to the existing capillarity of porous building materials. Its action may impair the performance of the walls of buildings, leading to their progressive degradation. Thus, the walls may cease to comply with their functions, such as protecting and finishing. Several treatments have been studied worldwide. However, evaluating the methods of repairing affected walls has been a difficult problem to be solved. The aim of this study is to evaluate the efficacy of the treatment of walls presenting upward moisture through the method of the crystallizing insertion through gravitational action using different available products within the Brazilian market. In spite of being limited to thin walls, this technique has presented efficacy, versatility of execution and little interference on the treated facade as it has been demonstrated on the studied bibliography. These features justify choosing that technique to be studied in the present work. A reference experiment conducted by other researchers is used, since there is no standard test to evaluate the efficiency of treatment products rising damp against. The evaluation of the moisture present in the specimen is by measuring the mass and images with thermographic camera. It was found that in the period analyzed, there was no reduction of the total moisture upward. However the crystallizing managed to reduce significantly (on average more than 50%) the absorption of water by capillarity.
