Heavy weight concrete or density concrete is commonly used for radiation shielding either in nuclear power plants or in radiation therapy units. It can also be used as ballast in offshore locations such as pipelines. Heavy weight concrete is designed by using heavy weight aggregates such as hematite, magnetite, barite etc. Here 2 heavy weight aggregates are used- hematite and laterite stone. First concrete mixes were prepared by replacing conventional aggregates with hematite (0%, 25%, 50% and 100 %). Then another set of mixes were prepared by replacing conventional concrete with laterite stones in the same percentage. Physical and mechanical properties of all the mixes were determined and then compared with the standard mix. The concrete with density up to 3004 kg/m3 was obtained for hematite concrete and density up to 2663 kg/m3 was obtained for laterite concrete.
