Pyrrhotite in Portuguese aggregates: a first insight

Ramos, V.; Fernandes, I.; Santos Silva, A. (Université Laval, 2024-05-15)

The presence of iron sulfides in aggregates can be responsible for severe concrete degradation. The oxidation of these minerals in the presence of humidity can lead to the formation of sulfate minerals, such as gypsum, ...
Effect of cow dung additions on tropical and mediterranean earth mortars

Pachamama, R.; Faria, P.; Rezende, M.; Santos Silva, A. (MDPI, 2024-06-13)

Cow dung (CD) is a material that has been used for millennia by humanity as a stabilizer in earth building techniques in vernacular architecture. However, this stabilization has been little addressed scientifically. In ...
Behaviour of CFRP composites and epoxy adhesives after long-term exposure to outdoor and laboratory-controlled environments

Durability under hygrothermal exposure of vacuum infused GFRP composites produced with polyester and vinyl ester resins

Hasan, T.; Correia, J. R.; Garrido, M.; Cabral-Fonseca, S.; J. SENA-CRUZ; Jorge, M. (NA, 2024-07)
Effects of thermal cycles on the mechanical and thermomechanical behaviour of vacuum infused GFRP composites

Hasan, T.; Correia, J. R.; Garrido, M.; Cabral-Fonseca, S.; J. SENA-CRUZ; Jorge, M. (NA, 2024-07)
An approach to accurately identifying binders in historic mortars by the combination of microscopic and microanalytical techniques

Almeida, L.; Santos Silva, A.; Veiga, M. R.; Mirão, J. (MDPI, 2024-08-21)

Mortars are among the most important materials in building construction. They are generally obtained by mixing aggregates with an inorganic binder. The identification of mortar constituents, particularly the binder type ...
Durability of GFRP composites produced by pultrusion under thermal environments

Hassanshahi, O.; Jorge, M.; J. SENA-CRUZ; Correia, L.; Hasan, T.; Correia, J. R.; Garrido, M.; Cabral-Fonseca, S.; Leite, C. (Elsevier, 2024-09)

Fibre-reinforced polymer (FRP) composites have gained popularity in civil structural applications due to their advantages over traditional materials. Despite their proven better performance in harsh conditions, FRP composites ...
Natural weathering of GFRP structures: Case studies, data survey and proposal of a moisture conversion factor for durability design

Rosa, I.; Castelo, A.; Sousa, J.; Garrido, M.; Correia, J. R.; Cabral-Fonseca, S.; Brito, J. (ASCE, 2024-09)

This paper defines a conversion factor included in the European technical specification for the design of fibre–polymer composite structures that considers the effects of moisture on the mechanical properties of fiber-reinforced ...
Durability of vacuum infused GFRP composites exposed to natural weathering

Hasan, T.; Correia, J. R.; Garrido, M.; Cabral-Fonseca, S.; J. SENA-CRUZ; Jorge, M. (NA, 2024-11)
