A 100% waste-based alkali-activated material by using olive-stone biomass ash (OBA) and blast furnace slag (BFS)

Font-Pérez, Alba; Soriano Martínez, Lourdes; Moraes, J.C.B; Tashima, M.M.; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Paya Bernabeu, Jorge Juan (Elsevier, 2017)

[EN] This study presents the use of olive-stone biomass ash (OBA) as an alkali source in alkali-activated materials (AAM) based on blast furnace slag (BFS). The OBA was physically and chemically characterized. It presented ...
Behavior of metakaolin-based geopolymers incorporating sewage sludge ash (SSA)

Istuque, D.B.; Reig Cerdá, Lucía; Moraes, J.C.B; Akasaki, Jorge Luis; Borrachero Rosado, María Victoria; Soriano Martínez, Lourdes; Paya Bernabeu, Jorge Juan; Malmonge, J.A.; Mitsuuchi Tashima, Mauro (Elsevier, 2016-10)

[EN] In recent years, geopolymers have become a widely researched binding material. There are technological and environmental advantages tousing this type of binder instead of Portland cement. In this study, binary systems ...
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 sugar cane straw ash (SCSA) as solid precursor and the alkaline activator composition on alkali-activated binders based on blast furnace slag (BFS)

Moraes, J.C.B; Mitsuuchi Tashima, Mauro; Akasaki, Jorge Luis; J.L.P.Melges; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Soriano Martínez, Lourdes; Paya Bernabeu, Jorge Juan (Elsevier, 2017)

[EN] Alkali-activated materials (AAM) comprise one of the solutions to diminish the use of Portland cement in building construction and, consequently, a reduction in the environmental problems related to CO2 emissions and ...
Improving the reactivity of a former ground sugarcane bagasse ash produced by autogenous combustion through employment of two different additional grinding procedures

Moraes, J.C.B.; Cordeiro, G.C.; Akasaki, J.L.; Vieira, A.P.; Paya Bernabeu, Jorge Juan (Elsevier, 2021-02-08)

[EN] Studies on reactivity of sugarcane bagasse ash (SCBA), obtained by an autogenous combustion process, with low loss on ignition and three different particle sizes were carried out (SCBA-1, SCBA-2 and SCBA-3). The ashes ...
Increasing the sustainability of alkali-activated binders: The use of sugar cane straw ash (SCSA)

Moraes, J.C.B; Mitsuuchi Tashima, Mauro; Akasaki, Jorge Luis; Pinheiro Melges, Jose Luis; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Soriano Martínez, Lourdes; Paya Bernabeu, Jorge Juan (Elsevier, 2016-09)

Alkali-activated binders are the new trend in building construction studies due their good mechanical properties and environmental advantages. These type of binders are obtained by a mixing of a solid precursor with an ...
Optimum use of sugar cane straw ash (SCSA) in alkali-activated binders based on blast furnace slag (BFS)

Moraes, J.C.B; Tashima, M.M.; Melges, J.L.P.; Akasaki, J.L.; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Soriano Martinez, Lourdes; Paya Bernabeu, Jorge Juan (American Society of Civil Engineers, 2018-06)

[EN] Alkali-activated binders (AABs) are a material obtained from the combination of a solid precursor and an alkaline activating solution. In this study, one solid precursor used was blast-furnace slag (BFS) and the other ...
Pozzolanic reactivity studies on a miomass-derived waste from sugar cane production: sugar cane straw ash (SCSA)

Moraes, J.C.B; Melges, J. L. P.; Akasaki, Jorge Luis; Tashima, M. M.; Soriano Martínez, Lourdes; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Paya Bernabeu, Jorge Juan (American Chemical Society, 2016-06)

Biomass has gained in importance as an energy source in recent years. One of the crops that presents interesting opportunities with regard to biomass is sugar cane. In Brazil, sugar cane production is increasing for alcohol ...
