Based on test results, the use of hematite and iron slag has been found to enhance the shielding properties of concrete subjected to 137 Cs and 60 Co point sources. Moreover, incorporating 30% hematite or iron slag led to significant enhancement in compressive strength, while the highest specific heat was obtained for 30% slag mixes.
