Desarrollo de geopolímeros estables para aplicaciones de purificación de agua

Martínez Fuertes, Maria (Universitat Politècnica de València, 2020-04-08)

[ES] El ràpid creixement de la societat i de la indústria ha incrementat la demanda d'aigua, la quantitat d'aigua residual produïda, així com de subproductes industrials perillosos. S'entén com a residu perillós qualsevol ...
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 ...
Effect of silicoaluminous pozzolans on the hydration process of the Portland cement cured at low temperatures

Soriano Martínez, Lourdes; Monzó Balbuena, José Mª; Bonilla Salvador, María Mercedes; Tashima, Mauro M.; Paya Bernabeu, Jorge Juan; Borrachero Rosado, María Victoria (Elsevier, 2013-09)

The aim of this paper is to study hydration processes in cement pastes and mortars, blended with either metakaolin (MK) or a catalyst used in catalytic cracking (FCC), and cured at low temperature. The amounts of hydrates ...
Evaluación mecánica y por espectroscopia de vibración de composites de GRC con diferentes tipos de matriz cementante

Castellese Monzó, Adriana (Universitat Politècnica de València, 2016-05-17)

[EN] Using non-destructive techniques based vibration spectroscopy, to assess the aging process of a fiber reinforced composite alkali-resistant glass (AR). For this purpose, we used two types of cementitious matrices: ...
Evaluation of the long-term compressive strength development of the sewage sludge ash/metakaolin-based geopolymer

Istuque, D.; Soriano Martinez, Lourdes; Borrachero Rosado, María Victoria; Paya Bernabeu, Jorge Juan; Akasaki, J. L.; Melges, J. L. P.; Tashima, M. M. (Departmento de Publicaciones del CSIC, 2021-09)

[EN] This paper aimed to evaluate the long-term compressive strength development of the sewage sludge ash/metakaolin (SSA/MK)¿based geopolymer. SSA/MK¿based geopolymeric mortars and pastes were produced at 25ºC with different ...
The effect of temperature on the geopolymerization process of a metakaolin-based geopolymer

Muñiz-Villarreal, M. S.; Manzano Ramirez, Alejandro; Sampieri-Bulbarela, S.; Gasca-Tirado, J. Ramón; Reyes-Araiza, José Luis; Rubio-Ávalos, José Carlos; Pérez Bueno, J. J.; Apatiga, L. M.; Zaldivar-Cadena, A.; Amigó Borrás, Vicente (Elsevier, 2011-03-31)

This paper describes the effect of different curing temperatures on the geopolymerization process, physical, mechanical and optical properties of a metakaolin-based geopolymer activated by alkali. The influence of different ...
