| Popis: | Alkali-activated materials, which some authors often call geopolymers, can be described as inorganic solids that form three-dimensional networks with molecular structure similar to organic polymers, and are able to combine qualities similar to cements with those of traditional ceramics and zeolites. The polymerisation reaction takes place between solid aluminosilicate powders and alkaline solutions at low temperature and therefore this process is classified as eco-efficient. In addition, this process allows the recycling of a large variety of amorphous aluminosilicate waste materials, which makes it very attractive from the environmental point of view. In this work, alkaline activated materials have been prepared using exclusively industrial and urban wastes to replace both, the aluminosilicate powder (from asphalt fillers and fluorescent lamps wastes) and the alkaline activator (from aluminium manufacturing industry). The materials obtained have been fully characterised. A mineralogical and microstructural study of these materials was conducted by FTIR, XRD, and ESEM-EDX. Moreover, it has been determined their bulk density, strength resistance, water absorption and leaching tests, confirming their suitability for being used as urban pavement. The work has been carried out thanks to a project, with reference IMAMCA/2016/1 - IMDEEA/2017/100, co-financed by the IVACE and the ERDF Funds, within the ERDF Operational Programme of the Valencia Region 2014–2020. Maria Criado expresses her gratitude to the European Research Council under the European Union's Seventh Framework Programme (FP/2007–2013)/ERC Grant Agreement #335928. Moreover, this research has performed in part at the MIDAS Facility, at The University of Sheffield, which was stablished with support from the Department of Energy and Climate Change. |
