Purpose – Infrared thermography is increasingly being used to diagnose pathologies in buildings, such as façade defects. The purpose of this paper assess the results reproducibility and equipment influence on measurements. To do so, it was defined case study assessment rendering delamination. Design/methodology/approach Two infrared cameras different makers were detect presence defects deliberately created specimens. tests done laboratory with a heat source. detected through temperature...
Facades play an important role in building performance and durability since these systems, one of the most external elements, are highly exposed to climatic degradation agents. The process evolves over time, causing anomalies failures, ultimately reducing building’s service life. When directly influenced by agents mechanisms, expected systems that constitute facade depends on degree exposure how mechanisms act under different conditions. Given relevance topic need for information this...

Resumo A incidência de agentes degradação sobre os edifícios é responsável pela origem mecanismos que levam ao desenvolvimento anomalias, as quais reduzem o desempenho dos sistemas do edifício. Nesse contexto, investigar a relação entre e fundamental para fornecer subsídios estudos vida útil materiais elementos mais duráveis. O objetivo deste estudo gravidade extensão da fachadas revestidas em argamassa, identificando padrões possam condicionar desse elemento. Essa abordagem se baseia na...
<p>No contexto da temática avaliação de desempenho, vida útil, degradação e diagnóstico patologias, tem-se observado que os edifícios construídos em Brasília vêm apresentando elevados casos manifestações patológicas nas fachadas. Esses fenômenos sendo observados mais diferentes idades, induzindo a questionamentos importantes na parte técnica, relacionados à compatibilidade dos materiais constituintes do sistema revestimento, técnicas construtivas, projeto. Neste sentido, o objetivo...
Abstract The objective of this article was to study the drying behavior rendering mortars. Cement-lime mortars with different mix proportions were evaluatedto analyze influence materials on water transport. experimental program produced observe transport liquid and vapor in during process. studied through capillary absorption by permeability test. curves used investigate kinetics obtained according methodology recommended European standard EN 16322. In summary, it is possible affirm that...
ResumenEn el presente trabajo se determina cómo ocurre transporte de agua, en sistema mortero/bloque, con objetivo vincular comportamiento la resistencia a adherencia por tracción perpendicular, agua y porosidad del substrato.Para ello fueron fabricados dos morteros áridos diferentes granulometrías, los cuales le determinó sus propiedades estado fresco endurecido.Se cantidad transportada, partir mediciones humedad sensores resistivos, camadas aplicados sobre sustrato hormigón cerámico.Los...
RESUMO O concreto autoadensável é de complexa obtenção, por isso exige-se um estudo minucioso da mistura e do seu comportamento no estado fresco. De acordo com os requisitos autoadensabilidade exigidos pela norma brasileira ABNT NBR 15823-1, decidiu-se obter parâmetros reologia meio estudos em argamassas e, posteriormente, concretos. Os decorrentes avaliação das foram obtidos dos seguintes ensaios: mini-slump, mini-funil caracterização reológica reômetro marca Rheotest N4.1. provenientes...
Resumo A identificação de anomalias para a elaboração mapas danos é uma tarefa complexa e depende do conhecimento das suas formas manifestação. O objetivo deste estudo propor critérios detecção em revestimentos argamassa, pela análise imagens fachadas, visando aperfeiçoar o mapeamento danos. São propostos parâmetros específicos, relacionados posição (geometria), configuração, agrupamento, origem componentes construtivos próximos que direcionam cada dano, indicando mais importante observar...
Facades are systems fixed externally to the building that perform function of protecting internal environment, thermal comfort and control lighting. The degradation facades occurs due action agents mechanisms capable causing alterations in chemical physical characteristics materials. It depends on factors such as orientation, degree exposure construction processes. Because have different conditions, manifests itself heterogeneously. Given need understand evolutionary behavior degradation, we...
The definition of models to evaluate the durability buildings can be a challenging task due large set variables, and their complexity, which affect performance buildings. Recently, several methodologies have been developed predict service life components. knowledge acquired through these allowed for adopting more rational sustainable solutions. This study proposes application artificial neural networks (ANNs) estimate ceramic claddings in Brasília, Brazil. variables that impact are...
