A Double Barrier Technique with Hydrotalcites for Pb Immobilisation from Electric Arc Furnace Dust
Lozano Lunar, Angélica; Fernández Ledesma, Enrique; Romero Esquinas, Álvaro; Jiménez Romero, José Ramón; Fernández Rodríguez, José María (MDPI, 2019)A new line of mortars incorporating hydrotalcites was developed. This research article shows the results of a study of a double barrier technique (DBT) for Pb immobilisation from electric arc furnace dust (EAFD) in mortars ... -
Accelerated Carbonation of Vibro-Compacted Porous Concrete for Eco-Friendly Precast Elements
Merino-Lechuga, Antonio Manuel; González-Caro, Ágata; Fernández Ledesma, Enrique; Jiménez, José Ramón; Fernández Rodríguez, José María; Suescum-Morales, David (MDPI, 2023)This research studied the effect of accelerated carbonation in the physical, mechanical and chemical properties of a non-structural vibro-compacted porous concrete made with natural aggregates and two types of recycled ... -
Carbon Emission Evaluation of CO2 Curing in Vibro-Compacted Precast Concrete Made with Recycled Aggregates
Suescum-Morales, David; Fernández Ledesma, Enrique; González-Caro, Ágata; Merino-Lechuga, Antonio Manuel; Fernández Rodríguez, José María; Jiménez, José Ramón (MDPI, 2023)The objective of the present study was to explore three types of vibro-compacted precast concrete mixtures replacing fine and coarse gravel with a recycled/mixed concrete aggregate (RCA or MCA). The portlandite phase found ... -
Mechanical behaviour of self-compacting concrete made with non-conforming fly ash from coal-fired power plants
Romero Esquinas, Álvaro; Fernández Ledesma, Enrique; Otero, R.; Jiménez, José Ramón; Fernández, José María (Elsevier, 2018)Currently, global sustainability depends on achieving integrated productivity in all economic sectors, making it possible to respond to the environmental challenges facing humanity at present. With the dual objective of ... -
Performance of Sustainable Mortars Made with Filler from Different Construction By-Products
López Uceda, Antonio; Fernández Ledesma, Enrique; Jiménez, José Ramón; Fernández Rodríguez, José María (MDPI, 2022)One way to contribute to sustainability in the construction sector is through the incorporation of construction by-products from their own activities. This work intends to extend the possibilities for enhancement of these ... -
The Effect of Acanthocardia tuberculata Shell Powder as Filler on the Performance of Self-Compacting Mortar
González-Caro, Ágata; Merino-Lechuga, Antonio Manuel; Fernández Ledesma, Enrique; Fernández Rodríguez, José María; González-Jiménez, José R.; Suescum-Morales, David (MDPI, 2023)In this research, the feasibility of using Acanthocardia tuberculata shell waste from the canning industry in the manufacturing of self-compacting mortar (SCM) was tested. The seashells were finely ground to be used as ... -
The role of pH on leaching of heavy metals and chlorides from electric arc furnace dust in cement-based mortars
Fernández Ledesma, Enrique; Lozano Lunar, Angélica; Ayuso Muñoz, Jesús; Pérez Galvín, Adela; Fernández, José María; Jiménez, José Ramón (Elsevier, 2018)Electric arc furnace dust (EAFD) presents a pollution hazard due to its heavy metal leachability. Its characterization is essential for recovery or disposal in hazardous waste landfills. The present work discusses the ...
