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 ...
Effect of porosity on the absorbed, reemitted and transmitted light by a geopolymer metakaolin base

Gasca-Tirado, J. Ramón; Rubio-Ávalos, José Carlos; Muñiz-Villarreal, M. S.; Manzano Ramirez, Alejandro; Reyes-Araiza, José Luis; Sampieri-Bulbarela, S.; Villaseñor-Mora, Carlos; Pérez Bueno, J. J.; Apatiga, L. M.; Amigó Borrás, Vicente (Elsevier, 2011-03-15)

In the present paper, the optical characterization of a geopolymer synthesized at three different temperatures (40, 60 and 90 °C) is described. The results were correlated to the porosity fraction in order to obtain a ...
Estabilización de suelos con geopolimeros: posibilidad de uso en países en desarrollo

Dios Puertas, Verónica de (Universitat Politècnica de València, 2019-10-23)

[ES] La tierra es un material abundante, que tiene un bajo coste económico y medioambiental, y que presenta buenas propiedades para su uso como material de construcción. Por estos motivos, se utiliza habitualmente, sobre ...
Geopolymer eco-cellular concrete (GECC) based on fluid catalytic cracking catalyst residue (FCC) with addition of recycled aluminium foil powder

Font-Pérez, Alba; Borrachero Rosado, María Victoria; Soriano Martínez, Lourdes; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan (Elsevier, 2017)

[EN] This study presents a new cellular concrete design focused on the energy eco-efficiency and the sustainability concept: geopolymer eco-cellular concrete (GECC). Geopolymer systems made from alkali-activated fluid ...
Hormigón celular geopolimérico (hcg) aireado con aluminio reciclado: desarrollo y caracterización de un material de bajo coste económico y medioambiental

Font Pérez, Alba (Universitat Politècnica de València, 2016-12-29)

[EN] Cellular Aerated Concrete (HCT, for its acronym in Spanish) is a Portland cement-based binder, which is added an inorganic reagent, generally aluminum powder. Metal aluminum is oxidized immediately when it comes in ...
Incorporation of photoactive TiO2 in an aluminosilicate inorganic polymer by ion exchange

Gasca-Tirado, José Ramón; Manzano Ramirez, Alejandro; Villaseñor-Mora, Carlos; Muñiz-Villarreal, M. S.; Zaldivar-Cadena, A. A.; Rubio-Ávalos, José Carlos; Amigó Borrás, Vicente; Nava Mendoza, Rufino (Elsevier, 2012-05-01)

In the present paper, it is described a procedure to ion exchange in an aluminosilicate inorganic polymer (geopolymer) in order to incorporate photoactive TiO 2. Metakaolin base geopolymers synthesized at 40 and 90 °C were ...
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 thermal characterisation of geopolymers based on silicate-activated metakaolin/slag blends

Bernal, Susan A.; Rodríguez Martínez, Erich David; Mejia De Gutierrez, Ruby; Gordillo, Marisol; Provis, John L. (Springer Verlag (Germany), 2011-08)

[EN] This article assesses the effect of mix design parameters on the compressive strength and thermal performance of alkali silicate-activated blends of metakaolin (MK) and granulated blast furnace slag (GBFS). A strong ...
New geopolymeric binder based on fluid catalytic cracking catalyst residue (FCC)

Mitsuuchi Tashima, Mauro; Akasaki, Jorge Luis; Castaldelli, V.N.; Soriano Martínez, Lourdes; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan; Borrachero Rosado, María Victoria (Elsevier, 2012-08)

This paper provides information about the synthesis and mechanical properties of geopolymers based on fluid catalytic cracking catalyst residue (FCC). FCC was alkali activated with solutions containing different SiO 2/Na ...
