Binary and ternary combinations of sewage sludge ash (SSA) with marble dust (MD), fly ash (FA) and rice husk ash (RHA) as replacement in Portland cement pastes, were assessed. Several tests were carried out at different ...
Effect of inorganics on the pyrolysis behaviour of agricultural residues.

Lechuga Romero, Rocío Marina (Universitat Politècnica de València, 2022-06-27)

[ES] Las condiciones medioambientales actuales han hecho necesario buscar y utilizar nuevas fuentes de energía, dando lugar a alternativas energéticas modernas como la biomasa. La energía de la biomasa es relativamente ...
Evaluación de la reactividad puzolánica de la ceniza de paja de arroz

Hidalgo Astudillo, Samantha Elizabeth (Universitat Politècnica de València, 2018-07-11)

The purpose of this aim is to determine the pozzolanic properties, as well as the physical and chemical characteristics of rice straw ash for use as an admixture in concrete mixtures with Portland cement. A material is ...
Evaluation of rice straw ash as a pozzolanic addition in cementitious mixtures

Hidalgo, Samantha; Soriano Martinez, Lourdes; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan; Font, Alba; Borrachero Rosado, María Victoria (MDPI AG, 2021-01)

[EN] Rice husk ash is one of the most widely studied biomass ashes used in pozzolanic addition. Given its lower silica content, rice straw ash (RSA) has been explored less often, despite the fact that, according to the ...
Inmobilization of Zn(II) in Portland cement pastes. Determination of microstructure and leaching performance

Mellado Romero, Ana María; Borrachero Rosado, María Victoria; Soriano Martínez, Lourdes; Paya Bernabeu, Jorge Juan; Monzó Balbuena, José Mª (Akadémiai Kiadó, 2013-06)

The aim of this paper is to study the solidification/ stabilization potential of cementitious matrices on the immobilization of Zn(II) before its disposal into the environment by determining the mechanisms of interaction ...
Polyvinyl alcohol nanofiber reinforced Nafion membranes for fuel cell applications

Mollá Romano, Sergio; Compañ Moreno, Vicente (Elsevier, 2011-04-15)

This work has been focused on the preparation and characterization of composite membranes with thickness between 19 and 97 mu m and containing Nafion(R) infiltrated into a porous mat obtained by electrospinning of an aqueous ...
Portland cement systems with addition of sewage sludge ash. Application in concretes for the manufacture of blocks

Baeza-Brotons, Francisco; Garces, Pedro; Paya, Jordi; Saval, José Miguel (Elsevier, 2014-11)
