3. DURABILITY OF HDPE GEOMEMBRANES: AN OVERVIEW
The polymer demand for geotechnical applications has been growing. The geomembrane is a geosynthetic, manufactured, polymeric product and is often specified in environmental projects. Geomembranes started to be used in the 1930s but became more widespread in the 1940s. In the 1970s, geomembranes began to be specified for landfills. Over the past forty years,

5. Investigating the Effect of Curing in the Chloride Diffusion Coefficient of Conventional Concrete
Concrete is the most used material in the construction industry worldwide. Built concrete infrastructure is exposed to specific environments conditions during the asset’s life, which impose chemical and physical actions that may lead to premature deterioration. Poor concrete durability and corrosion of reinforcement bars are the primary cause of structural

8. Efeito da adição de fibras híbridas na durabilidade de compósitos cimentícios avançados em ambientes úmidos e agressivos
ABSTRACT Reactive powder concrete (RPC) is one type of advanced cementitious composite that has been increasingly used. Its high mechanical strength enables the application of the composite in bolder structures. Considering its recent history of use, there is a lack of knowledge about this materials durability. Therefore, this paper aimed to evaluate the beh

9. Corrosión atmosférica acelerada en una fundición gris ASTM A48
ABSTRACT Due to the long times required to investigate atmospheric corrosion resistance of metals, data on the subject is scarce. One of these studies is the one made by Southwell et al., where the effect of corrosion in a cast gray iron during 16 years was studied in various environments. This research shows and discusses the behavior of cast gray iron when

10. Mechanical behavior of yttria-stabilized tetragonal zirconia polycrystal: Effects of different aging regimens
Abstract This study aimed to characterize and compare the effect of different aging regimens on surface characteristic (topography and roughness), structural stability (phase transformation) and mechanical performance (Weibull analysis) of a Y-TZP ceramic. Discs (15 × 1.2 mm; VITA In-Ceram YZ) were prepared according to ISO 6872-2015 for biaxial flexural st

12. Comparative Assessment of stabilised Polybutadiene Binder under Accelerated Ageing
ABSTRACT Polybutadiene elastomers are versatile materials, being employed at several applications from rocket propellant binder to adhesives and sealants. The elastomers derived from hydroxyl-terminated polybutadiene are usually stabilised with antioxidants to prevent degradation. In this study, a comparative assessment among 2,2’-methylene-bis (4-methyl-6
