Experimental Study on Hematite Concreting
High Density concrete is commonly used for radiation shielding of nuclear-reactors and other structures like counter weights, coating of off-shore pipelines. High Density concrete or is designed by using heavy weight aggregates such as hematite, magnetite, barite etc. The material is called hematite is used in this special concrete. The mix used is for OPC 43grade of cement. High density concrete can be designed in same way as normal weight concretes, but the additional self-weight should be taken into account.
