Magnesium phosphate cement incorporating sheep wool fibre for thermal insulation applications

Autor: Maldonado Alameda, Alex, Alfocea Roig, Anna, Huete Hernández, Sergio, Giró Paloma, Jessica, Chimenos Ribera, Josep Ma., Formosa Mitjans, Joan

The increasing use of synthetic fibres in clothing and the high quality of sheep wool fibre (SWF) from the Australian and New Zealand market leads to a decline in the interest in SWFs produced in European countries, considering them as waste that cou

Sustainable magnesium phosphate micromortars formulated with PAVAL® alumina by-product as micro-aggregate

Autor: Huete Hernández, Sergio, Maldonado Alameda, Alex, Alfocea Roig, Anna, Giro Paloma, Jessica, Chimenos Ribera, Josep Ma., Formosa, Joan

Publikováno v: Boletín de la Sociedad Española de Cerámica y Vidrio.

Magnesium phosphate cement (MPC) is an attractive alternative to Portland cement (PC) since it can also be obtained using by-products and wastes as raw materials. This research uses low-grade MgO (LG-MgO) as a magnesium source to obtain MPC, reducing

This work aims to assess the potential reactivity of a mechanically activated kaolin for its use as an alternative cement precursor. The mechanical activation was successfully achieved by grinding at different rotation speeds (250, 300, and 350 rpm)

Kaolinite structural modifications induced by mechanical activation

Autor: Mañosa Bover, Jofre, Calvo de la Rosa, Jaume, Silvello, A. (Alessio), Maldonado Alameda, Alex, Chimenos Ribera, Josep Ma.

Publikováno v: Applied Clay Science. 238:106918

This study presents novel characterisation techniques to evaluate the effects of mechanical activation (MA) on the kaolinite structure. MA was achieved with a planetary ball mill at various times and rotation speeds to get different activation degree

Weathered bottom ash from municipal solid waste incineration: Alkaline activation for sustainable binders

Autor: Maldonado Alameda, Alex, Giró Paloma, Jessica, Andreola, Fernanda, Barbieri, Luisa, Chimenos Ribera, Josep Ma., Lancellotti, Isabella

Publikováno v: Dipòsit Digital de la UB
Universidad de Barcelona

Alkali-activated binders (AABs) stand out as promising candidates to replace ordinary Portland cement (OPC) since waste can be used as raw material for their manufacture. This study addresses the environmental feasibility of using weathered bottom as
