Rights accessOpen Access
Oxidation 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, and the oxidation of the sulfide is the rate-limiting reaction. A model is presented to evaluate the kinetic evolution of expansion due to sulfide oxidation, and subsequent sulfate attack on the paste.

Study of the recycled aggregates nature's influence on the aggregate-cement paste interface and ITZ Sidorova, Anna; Vázquez Ramonich, Enric; Barra Bizinotto, Marilda; Roa Rovira, Joan Josep; Jiménez Piqué, Emilio (2014)
Restricted access - publisher's policyToday it is highly recognized that the structure of the cement paste matrix close to the aggregates, is different from the rest of the cement paste. This investigation compares the possible interfacial transition zone (ITZ) ...
