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 ... -
Geopolymer concrete with treated recycled aggregates: Macro and microstructural behavior
Pawluczuk, Edyta; Kalinowska-Wichrowska, Katarzyna; Jiménez, José Ramón; Fernández Rodríguez, José María; Suescum-Morales, David (Elsevier, 2021)Geopolymer concrete is a more environmentally friendly alternative than conventional concrete because its production does not need cement. Instead, waste materials such as fly ash, rice husk ash, slag, etc. are used. This ... -
Optimisation of mortar with Mg-Al-Hydrotalcite as sustainable management strategy lead waste
Lozano Lunar, Angélica; Álvarez, José Ignacio; Navarro-Blasco, Íñigo; Jiménez, José Ramón; Fernández Rodríguez, José María (MDPI, 2021)This study analyses how a Mg-Al-Hydrotalcite with carbonate in the interlayer influences the hydration of mortar allowing the management of lead waste (solid or liquid) in a cement-based material. First, the compatibility ... -
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 ... -
Preliminary Study of Recycled Aggregate Mortar for Electric Arc Furnace Dust Encapsulation
Ledesma, Enrique F.; Lozano Lunar, Angélica; Ferreira, Ruan L. S.; Fernández Rodríguez, José María; Jiménez, José Ramón (MDPI, 2021)This article shows the preliminary results of a study carried out to determine the technical feasibility of encapsulating a high percentage of EAFD in cement-based mortars manufactured with the fine fraction of recycled ... -
Ternary Blends for Self-Compacting Mortars Production Composed by Electric Arc Furnace Dust and Other Industrial by-Products
López Uceda, Antonio; Cantador Fernández, David; Raposeiro Da Silva, Pedro; Brito, Jorge de; Fernández Rodríguez, José María; Jiménez, José Ramón (MDPI, 2022)This study is framed within the circular economy model through the valorisation of industrial by-products. This research shows the results of producing self-compacting mortars (SCMs) with electric arc furnace dust (EAFD) ... -
The Performance of Concrete Made with Secondary Products—Recycled Coarse Aggregates, Recycled Cement Mortar, and Fly Ash–Slag Mix
Kalinowska-Wichrowska, Katarzyna; Pawluczuk, Edyta; Bołtryk, Michał; Jiménez, José Ramón; Fernández Rodríguez, José María; Suescum-Morales, David (MDPI, 2022)The properties of cement concrete using waste materials—namely, recycled cement mortar, fly ash–slag, and recycled concrete aggregate—are presented. A treatment process for waste materials is proposed. Two research experiments ... -
Use of Carbonated Water as Kneading in Mortars Made with Recycled Aggregates
Suescum-Morales, David; Jiménez, José Ramón; Fernández Rodríguez, José María (MDPI, 2022)The increased concern about climate change is revolutionising the building materials sector, making sustainability and environmental friendliness increasingly important. This study evaluates the feasibility of incorporating ...
