Chromium behavior during cement-production processes: A clinkerization, hydration, and leaching study

► Behavior of chromium during cement-production processes. ► Formation of new chromium compounds in clinker with chromium oxidation states of +3, +4.6, +5, and +6. ► Addition of chromium altered the composition of the clinker phases, setting time, and compressive strength of hydrated mixes. ► Cr3+ and Cr6 were leached during leaching tests, whereas other species remained in the mortar.
