Abstract
Process for solidifying radioactive waste wherein the waste is in solid or aqueous, flowable or liquid form, by mixing the waste with a binder to form a mixture and then leaving the mixture to harden. A mixture of the waste, the binder and an additive which is natural volcanic rock detritus, is formed. The detritus has a total content of CaO+MgO up to a maximum of 6.5 percent by weight and less than 50 percent by weight of residue insoluble in mineral acid. The detritus additive is mixed in an amount between 1 percent by weight and 60 percent by weight of the binder employed.
