Portland cement (PC) is a widely recognised binder for the immobilisation of intermediate level radioactive waste (ILW). However, this system has limited efficiency due to the high alkalinity associated with PC, which yields extremely aggressive leachates under the repository conditions. Moreover, the manufacture of PC is not only exceedingly resource and energy demanding, but it also has highly detrimental environmental impacts. Hence, with the objective of address the mentioned issues, this research has been focused on developing new binder systems with lower or no contents of PC. Two novel cementitiuous materials based on magnesium phosphate (MPC) and reactive magnesium oxide (MgO) were investigated. Methodology entailed the development of geochemical models and statistic optimisation of formulations. Further details including the obtained results will be present during this talk.
