A Novel Artificial Neural Network to Predict Compressive Strength of Recycled Aggregate Concrete
Suescum-Morales, David; Salas-Morera, Lorenzo; Jiménez, José Ramón; García-Hernández, Laura (MDPI, 2021)Most regulations only allow the use of the coarse fraction of recycled concrete aggregate (RCA) for the manufacture of new concrete, although the heterogeneity of RCA makes it difficult to predict the compressive strength ... -
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 ... -
Effect of the Composition of Mixed Recycled Aggregates on Physical–Mechanical Properties
López Uceda, Antonio; Fernández Ledesma, Enrique; Salas-Morera, Lorenzo; Jiménez, José Ramón; Suescum-Morales, David (MDPI, 2021)Recycled aggregates (RA) from construction and demolition waste are an alternative to natural aggregates in the construction sector. They are usually classified according to their composition. The main constituent materials ... -
Feasible use of colliery spoils as subbase layer for low-traffic roads
Suescum-Morales, David; Romero Esquinas, Álvaro; Fernández Ledesma, Enrique; Fernández, José M.; Jiménez, José Ramón (Elsevier, 2019)The aim of this paper is to characterise, both physically and chemically, the colliery spoils of Pozo San José, located in the Guadiato Valley (Córdoba, Spain), and evaluate their possible use as unbound materials or as ... -
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 ... -
Materiales de construcción captadores de CO2 para mitigación del cambio climático
Suescum-Morales, David (Universidad de Córdoba, UCOPress, 2022)La contaminación ambiental, el agotamiento de los recursos no renovables, la gran cantidad de residuos generados, el concepto de “usar y tirar/use and throw” y el aumento de los gases efecto invernadero (GHG), especialmente ... -
Optimising the Performance of CO2-Cured Alkali-Activated Aluminosilicate Industrial By-Products as Precursors
Lamaa, Ghandy; Suescum-Morales, David; Duarte, António P. C; Vasco Silva, Rui; Brito, Jorge de (MDPI, 2023)Three industrial aluminosilicate wastes were studied as precursors to produce alkali-activated concrete: (i) electric arc furnace slag, (ii) municipal solid waste incineration bottom ashes, and (iii) waste glass rejects. ... -
Review of the Application of Hydrotalcite as CO2 Sinks for Climate Change Mitigation
Suescum-Morales, David; Jiménez, José Ramón; Fernández Rodríguez, José María (MDPI, 2022)In recent decades, the environmental impact caused by greenhouse gases, especially CO2, has driven many countries to reduce the concentration of these gases. The study and development of new designs that maximise the ... -
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 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 ...
