[As I was reading this article I was thinking about Rome’s Monte Testaccio, an “artificial mound[s] in Rome composed almost entirely of testae, fragments of broken ancient Roman pottery, nearly all discarded amphorae [mainly for imported olive oil] dating from the time of the Roman Empire…”: https://en.wikipedia.org/wiki/Monte_Testaccio]

#Cement made with iron #slag has been widely used since decades. For example type IIIC have 83-95% of slag content. Slag cements yet have a very slow setting time. We'll see if they really get actual #clinker (Portland cement is a mix of clinker, gypsum and usually limestone)
