Pozzolanic activity of tiles, bricks and ceramic sanitary-ware in eco-friendly Portland blended cements

Pitarch, A. M.; Reig Cerdá, Lucía; Tomas, A. E.; Forcada, G.; Soriano Martinez, Lourdes; Borrachero Rosado, María Victoria; Paya Bernabeu, Jorge Juan; Monzó Balbuena, José Mª (Elsevier, 2021-01-10)

[EN] Reusing ceramic waste as a pozzolanic admixture may offer environmental benefits as it allows the reduction in the consumption of natural resources and energy, and the reduction of CO2 emissions associated with Portland ...
Reducción de la resistencia a compresión del hormigón en piezas hormigonadas verticalmente

Cantero López, Eva María (Universitat Politècnica de València, 2018-09-03)

Este trabajo trata de justificar la desaparición del factor de reducción de la resistencia a compresión en piezas hormigonadas verticalmente, que fue obligatorio utilizar en España en los cálculos de estructuras desde el ...
Reutilisation of hazardous spent fluorescent lamps glass waste as supplementary cementitious material

Pitarch, A.M.; Reig, L.; Gallardo, A.; Soriano Martinez, Lourdes; Borrachero Rosado, María Victoria; Rochina, S. (Elsevier, 2021-07-19)

[EN] Spent fluorescent lamps glass (SFLG) waste, manually and mechanically processed in a lamps waste treatment plant, was used to partially replace up to 50 wt% Portland cement (PC). Both waste types exhibited similar ...
Sea ice strength development from freezing to melting in the Antarctic marginal ice zone

Paul, Felix; Mielke, T.; Audh, R.; Lupascu, D.C. (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] Sea ice growth in the Marginal Ice Zone of the Antarctic is one of the largest annual changes on earth with a huge impact on the global climate and ecology system. The principles of sea ice growth and melting in the ...
Shrinkage of self-compacting concrete made with blast furnace slag as fine aggregate

Valcuende Payá, Manuel Octavio; Benito, F.; Parra, C.; Miñano, I. (Elsevier, 2015-02)

[EN] The aim of this experimental work was to study shrinkage evolution with age in self-compacting concretes (SCC) in which part of the fine aggregate was replaced by granulated blast furnace slag (GBFS) as sand. Seven ...
Stiffness variation of porous titanium developed using space holder method

Reig Cerdá, Lucía; Amigó Borrás, Vicente; Busquets Mataix, David Jerónimo; Calero, José Antonio (Maney Publishing, 2011-07)

The excellent properties of Ti have resulted in its generalised use for bone implants. However, Ti is very stiff in comparison with human cortical bone, and this creates problems of bone weakening and loosening of the ...
Study of the binary system fly ash/sugarcane bagasse ash (FA/SCBA) in SiO2/K2O alkali-activated binders

CASTALDELLI, V.N.; Moraes, J.C.B; Akasaki, Jorge Luis; Pinheiro Melges, Jose Luis; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Soriano Martínez, Lourdes; Paya Bernabeu, Jorge Juan; Mitsuuchi Tashima, Mauro (Elsevier, 2016-06)

Due environmental problems related to Portland cement consumption, many studies have been performed to diminish its use. One solution is the development of alkali-activated binders, which can decrease CO2 emissions and ...
Sustainable soil-compacted blocks containing blast furnace slag (BFS) activated with olive stone biomass ash (OBA)

Paya Bernabeu, Jorge Juan; Monzó Balbuena, José Mª; Rosello Caselles, Josefa; Borrachero Rosado, María Victoria; Font-Pérez, Alba; Soriano Martinez, Lourdes (MDPI AG, 2020-12)

[EN] Soil stabilization using cementing materials is a well-known procedure for earth-based building blocks preparation. For the selected binding materials, innovation usually focuses on low carbon systems, many of which ...
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 ...
Valorization of sugarcane bagasse ash (SCBA) with high quartz content as pozzolanic material in portland cement mixtures

Pereira, A.M.; Moraes, J.C.B; Bassan de Moraes, M.J.B.; Akasaki, J.L.; Tashima, M.M.; Soriano Martinez, Lourdes; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan (Departmento de Publicaciones del CSIC, 2018-04)

[EN] Portland cement (OPC) production is one of the most contaminating greenhouse gas producing activities. In order to reduce OPC consumption, several alternatives are being assessed, and the use of pozzolanic material ...
