Amorphous calcium carbonate (ACC) in fresco mural paintings
(2020-05-01)
Article
Accés obertA fresco painting has a calcium carbonate binder produced as result of the carbonation process of a lime paste. The reaction environmental conditions are similar to those of bio-mineral formation where an amorphous calcium ... -

(2022-07)
Article
Accés obertA fresco painting has a calcium carbonate binder produced as result of the carbonation process of a lime paste. The reaction environmental conditions are similar to those of bio-mineral formation where an amorphous cal-cium ... -
Carbonation of ternary building cementing materials
(2012-11)
Article
Accés restringit per política de l'editorialThe carbonation processes of ettringite and calcium aluminate hydrates phases developed by hydration of calcium aluminate cement, fly ash and calcium sulphate ternary mixtures have been studied. The hydrated samples were ... -
Carbonation resistance of recycled aggregate concrete using different cement types
(Springer, 2023)
Capítol de llibre
Accés restringit per política de l'editorialThis paper describes the influence of the cement type and the use of 50% coarse RCA on the carbonation resistance of concrete. Twelve concrete mixtures were produced using four types of cement (CEM I, CEM IIAL, CEM IIAS ... -
Coupling of attrition and accelerated carbonation for CO2 sequestration in recycled concrete aggregates
(Elsevier BV, 2021-07)
Article

Durable structural concrete produced with coarse and fine recycled aggregates using different cement types
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-10)
Article
Accés obertThe durability properties of structural recycled aggregate concrete (RAC) produced with 50% coarse recycled concrete aggregates and up to 20% fine recycled concrete aggregates were analysed and compared to those of ... -
Evaluation of eco-efficient concretes produced with fly ash and uncarbonated recycled aggregates
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-12)
Article
Accés obertThe fabrication of conventional concrete, as well as remains from demolition, has a high environmental impact. This paper assessed the eco-efficiency of concrete made with uncarbonated recycled concrete aggregates (RCA) ... -
Experimental study of cement degradation under acid attack
(Universitat Politècnica de Catalunya, 2022-02-16)
Projecte Final de Màster Oficial
Accés obertL'emmagatzematge de diòxid de carboni en dipòsits abandonats de petroli/gas es considera una de les estratègies proposades per reduir les emissions de gasos d'efecte hivernacle a l'atmosfera. No obstant això, per l'exploració ... -
How the carbonation treatment of different types of recycled aggregates affects the properties of concrete
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-02)
Article
Accés obertIn this research work, two types of recycled aggregates were used: (1) the recycled concrete aggregate, RCA, obtained by crushing the parent concrete produced using limestone cement and (2) the recycled concrete aggregate ... -
Influence of high volume fly ash and recycled aggregates in chloride and carbonation resistance of concrete
(Centro Internacional de Métodos Numéricos en Ingeniería (CIMNE), 2020)
Text en actes de congrés
Accés obertThis paper deals with the evaluation of the influence of recycled concrete aggregate (RCA) and the employment of high volume of fly ash (FA) on the physical, mechanical and durability (chloride ion penetration and carbonation) ... -

Projecte Final de Màster Oficial
Accés obertCatalà: L’estudi aquí presentat pretén millorar les qualitats dels àrids reciclats mitjançant un tractament superficial. La metodologia desenvolupada ha posat en pràctica diferents mètodes d’impregnació utilitzant àrids ... -
Report of RILEM TC 281-CCC: outcomes of a round robin on the resistance to accelerated carbonation of Portland, Portland-fly ash and blast-furnace blended cements
(2022-04)
Article
Accés restringit per política de l'editorialMany (inter)national standards exist to evaluate the resistance of mortar and concrete to carbonation. When a carbonation coefficient is used for performance comparison of mixtures or service life prediction, the applied ...
