Accelerated aging methods are becoming increasingly common to evaluate geotextile properties in long-term behavior. Due this, various manufacturers of these materials asked guarantee the useful life product, especially for components that cannot be easily inspected or may fail service. Although durability geotextiles non-demanding applications has traditionally been predicted from previous in-service experience, design harsh environments long term requires a much better understanding...
Humidity, air temperature, rainfall and solar radiation all contribute to the weathering of geosynthetics. Over time, their useful life can be affected changes in properties observed, which affects performance these materials. As geosynthetics durability analyses must encompass each work condition, assessing climate effects is essential for design purposes. This study exposed a nonwoven needle-punched poly(ethylene) terephthalate geotextile natural three Brazilian cities (different exogenous...
Ornamental stones weaken with exposure to weathering. Consequently, anomalies such as disintegration and cracks appear, making degradation studies necessary. Durability are necessary determine the useful life of material. In this study, gneiss specimens were divided into three lots: first was a standard specimen, not aged, used control; second subjected accelerated in laboratory; third degraded naturally under local weathering conditions. After two processes, weakening stone from wear...
Resumo Este artigo traz um estudo sobre compósito de cimento, resíduo industrial lodo papel e flakes PET, visando sua potencialização para possível destinação em sistemas urbanos moradias baixo custo. Justifica-se pelos problemas socioambientais relacionados aos consumos matérias-primas naturais pela deposição indevida produtos resíduos no ambiente. Para isso, foram testadas as proporções 1:3, 1:4 1:5 cimento resíduos, com substituições do volume por PET nas taxas 10%, 20% 30%. Foram...
O município de Quissamã localiza-se na Microrregião Macaé/RJ, emancipado em 1989. Tem como principais atividades econômicas criação bovinos, cultura da cana açúcar, coco verde e abacaxi. desenvolvimento ocorreu forma acelerada desordenada após sua emancipação, gerando maior demanda água ocasionando problemas no abastecimento. Objetiva-se avaliar a hidroquímica das águas subterrâneas do município. Foi criada base dados georreferenciados para elaboração mapas, realizadas análises hidroquímicas...
Mass movements are continuous natural phenomena and external dynamics, like weathering erosion processes. The study presents an analysis of mass along the BR101 highway in Campos dos Goytacazes, Rio de Janeiro. For this purpose, a field survey was carried out, which causes 13 occurrences were identified analyzed. related to deficiency maintenance drainage ways, associated with activities, region average susceptibility erosion. presented offer low risk population.
Este trabalho apresenta estudo realizado em um gnaisse de Santo Antonio Padua / RJ BR e inclui a analise da durabilidade desta rocha, utilizando o ensaio slake durability . As rochas sao utilizadas, na maioria dos casos, aplicacoes como ornamentais. Para avaliar influencia rotacao neste ensaio, foi criado equipamento laboratorio que permite variar velocidade 7 RPM para 238 RPM. poderia ser grande variedade materiais rochosos e, assim, determinar seu tempo vida no projeto. Com variacao niveis...
