Aggregate expansivity due to sulfied oxidation - I. Reaction system and rate model
(Aggregate expansivity due to sulfied oxidation - I. Reaction system and rate model, 1996)
Article
Accés obertOxidation and hydration of sulfides in aggregate materials can yield to expansive reactions that affect the durability of concrete. This process is, in principle, independent from the potential alkali-aggregate reactivity, ... -

Evolution of pyrrhotite oxidation in aggregates for concrete
(2014-11-17)
Article
Accés obertRocks containing pyrrhotite bands are sometimes used to produce concrete. These rocks oxidize and produce long-term expansive reactions that damage concrete structures, leading to important economic and risk related ... -
Non-destructive screening methodology based on handheld XRF for the classification of concrete: cement type-driven separation
(2023-04)
Article
Accés obert -
Thermo-mechanical stability of concrete containing steel slag as aggregate after high temperature thermal cycles
(2022-06)
Article
Accés obertThermal energy storage represents a crucial element to increase solar power dispatchability. Within sensible heat storage in solid media, concrete is considered a low-cost alternative to be further developed and therefore, ...
