Blending of industrial waste from different sources as partial substitution of portland cement in pastes and mortars

Baeza, F.; Paya Bernabeu, Jorge Juan; Galao Malo, Oscar; Saval, J.M.; Garcés, Pedro (Elsevier, 2014-09)

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 ...
Compressive strength and microstructure of alkali-activated blast furnace slag/sewage sludge ash (GGBS/SSA) blends cured at room temperature

Tashima, M.M.; Reig, L.; Santini, M. A., Jr.; Moraes, J.C.B; Akasaki, J. L.; Paya Bernabeu, Jorge Juan; Borrachero Rosado, María Victoria; Soriano Martinez, Lourdes (Springer-Verlag, 2017-07)

[EN] In the present work, ground granulated blast furnace slag (GGBS) and sewage sludge ash (SSA) blends were assessed for the production of alkali-activated pastes and mortars. Percentages of SSA to substitute GGBS ranged ...
Effect of sewage sludge ash on mechanical and microstructural properties of geopolymers based on metakaolin

Istuque, D.B.; Soriano Martinez, Lourdes; Akasaki, J.L.; Melges, J.L.P.; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan; Tashima, M.M. (Elsevier, 2019-04-10)

[EN] This paper explored the effect of sewage sludge ash (SSA) on the mechanical and microstructural properties of geopolymers based on metakaolin (MK) involving two different SiO2/Na2O molar ratios (0.8 and 1.6), two ...
The role of dissolved rice husk ash in the development of binary blast furnace slag-sewage sludge ash alkali-activated mortars

Istuque, Danilo Bordan; Paya Bernabeu, Jorge Juan; Soriano Martinez, Lourdes; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Mitsuuchi Tashima, Mauro (Elsevier, 2022-07-15)

[EN] This study evaluated the compressive strength performance and microstructure of binary blast furnace slag-sewage sludge ash (BFS-SSA) alkali-activated mortars, in which rice husk ash (RHA) was dissolved in NaOH solution ...
Utilización de geopolímero para la mejora de las propiedades en morteros cal-puzolana y su empleo en países en desarrollo.

Villca Pozo, Ariel Rey (Universitat Politècnica de València, 2021-09-02)

[ES] El descubrimiento del cemento Portland ha cambiado nuestra forma de construir, pero también es el responsable de grandes emisiones de CO2 a la atmósfera durante su fabricación (~1450 ᴼC), agravando la crisis actual ...
