A binder from alkali activation of FCC waste: use in roof tiles fabrication

Mas, María Antonia; Mitsuuchi Tashima, Mauro; Paya Bernabeu, Jorge Juan; Borrachero Rosado, María Victoria; Soriano Martínez, Lourdes; Monzó Balbuena, José Mª (Trans Tech Publications, 2016)

Nowadays, scientific community is looking for alternatives to reduce the problem of CO2 emissions, making more sustainable binders and reusing wastes from other industries. In this line, the technology of geopolymers was ...
A new geopolymeric binder from hydrated-carbonated cement

Paya Bernabeu, Jorge Juan; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Soriano Martínez, Lourdes; Mitsuuchi Tashima, Mauro (Elsevier, 2012-05)

This paper evaluates the use of hydrated Portland cement as the raw material in the production of geopolymers. The silicon and aluminium oxides needed for the geopolymerization process were produced by the carbonation of ...
Compressive strength and microstructure of alkali-activated mortars with high ceramic waste content

Reig, L.; Sanz, M.A.; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Soriano Martínez, Lourdes; Paya Bernabeu, Jorge Juan (Elsevier, 2017)

[EN] The present work investigated alkali-activated mortars with high ceramic waste contents. Tile ceramic waste (TCW) was used as both a recycled aggregate (TCWA) and a precursor (TCWP) to obtain a binding matrix by the ...
Durabilidad de cementos activados alcalinamente: Resistenica al ataque ácido

Pérez Ramos, Martha Iris (Universitat Politècnica de València, 2016-09-12)

[EN] Nowadays, the emissions of carbon dioxide (CO2) to the atmosphere from the production of Portland cement clinker are approximately 1.00 kg per kilogram of cement manufactured. Study the durability of alternative ...
Estudio comparativo de la difusión de cloruros en pastas y morteros de cemento portland y activación alcalina

Mercedes Cedeno, Luis Enrique (Universitat Politècnica de València, 2014-10-30)

La contaminación por cloruros del hormigón es causa frecuente de corrosión de las armaduras de acero y por lo tanto del deterioro del hormigón. Debido a que la forma en que los cloruros pueden ingresar en una matriz de ...
Estudios preliminares sobre cemento hidratado para su reutilización en geopolímeros

Segura-Sierpe, Yasna Pamela; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan (Universidad Nacional de Colombia, 2016-04)

[EN] The carbonation of hydrated ordinary Portland cement (OPC) allows the transformation of hydrated calcium aluminates and silicates into calcium carbonate and amorphous silica/ alumina. These carbonated materials are ...
Influence of calcium additiions on the compressive strength and microstructure of alkali-activated ceramic sanitaryware

Reig, L.; Soriano Martinez, Lourdes; Tashima, M.M.; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan (Blackwell Publishing, 2018)

[EN] The ceramic sanitary-ware market generates large amounts of waste, both during the production process and due to construction and demolition practices. In this paper, the effect of different amounts and calcium sources ...
Mechanical and durability properties of alkali-activated mortar based on sugarcane bagasse ash and blast furnace slag

Pereira, Adriana; Akasaki, Jorge Luis; Melges, José L.P.; Mitsuuchi Tashima, Mauro; Soriano Martínez, Lourdes; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan (Elsevier, 2015-12)

Sugarcane bagasse is an agricultural waste which can be transformed, for cementing purposes, into an interesting material by combustion. Specifically, the ash (SBA) obtained by auto-combustion was used for preparing ...
