    • 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 ...

    • Functional and structural parameters of a paved road section constructed with mixed recycled aggregates from non-selected construction and demolition waste with excavation soil 

      Tavira, Javier; Jiménez, José Ramón; Ayuso Muñoz, Jesús; Sierra, María José; Fernández Ledesma, Enrique (Elsevier, 2018)
      This paper evaluates the lab and in situ mechanical properties of non-selected mixed recycled aggregates from construction and demolition waste (CDW) used as base and subbase unbound materials. Excavation materials are ...

      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 ...

    • Mobilizing greater crop and land potentials sustainably 

      Kassam, Amir; Basch, Gottlieb; Friedrich, Theodor; González Sánchez, Emilio Jesús; Triviño Tarradas, Paula María; Mkomwa, Saidi (Geographical Institute, Research Centre for Astronomy and Earth Sciences (CSFK), 2017)
      The supply side of the food security engine is the way we farm. The current engine of conventional tillage farming is faltering and needs to be replaced. It is faltering because it causes unacceptable level of soil erosion ...

    • Mechanical canopy and trunk shaking for the harvesting mechanization of table olive orchards 

      Sola Guirado, Rafael Rubén; Castillo-Ruiz, Francisco J.; Blanco Roldán, Gregorio L.; González Sánchez, Emilio Jesús; Castro García, Sergio (Universidad Nacional de Cuyo; Facultad de Ciencias Agrarias; Centro Coordinador de Ediciones Académicas, 2020)
      Table olive harvesting is highly dependent on manual labour and may jeopardize the crop benefit. The introduction of a mechanical harvest system requires a global evaluation of the whole process. A trunk shaker along with ...
