measurements on concrete containing hematite. Local hematite stones were used as aggregates to produce high density concrete for application in X-and gamma shielding. Concrete cube samples (150mm x 150mm x 150mm) containing hematite as coarse aggregates were prepared by changing mix ratio, water to cement ratio (w/c) and types of fine aggregate.

Large ore bodies of hematite are usually of sedimentary origin, and it is widely distributed in sedimentary rocks as a cement. High grade ore bodies can be found in metamorphic rocks as a result of contact metasomatism. Hematite is also as an accessory mineral in igneous rocks. The red colouring of soils all over the planet is due to hematite.
