Expansion project radiation oncology unit.Dense concrete blocks for a research facility.First LKAB Minerals project for radiation shielding in the 1960’s.Our radiation shielding experience and moreįinally, we have more detailed online information on different radiation shielding projects: Luckily, we can help you select the aggregate size you need to create the right density of concrete for your project. Moreover, you can use your equipment effectively to handle a heavy concrete just as you can for ordinary concrete. Of course, it is important to understand that the weight of MagnaDense will have an influence on the equipment you use. Fortunately, heavy concrete can be produced using standard construction equipment. In general, building a radiation shielding wall is usually not an everyday job for most companies. Reduced risk of cracking due to the high heat retention of MagnaDense which results in a lower peak in heat of hydration.Good radiation shielding characteristics.More weight, less volume less excavation/transportation/reinforcement and time for construction.You will see that depending on your project one or more of these benefits may apply: However, there is not one reply that fits all. We often get asked what advantages MagnaDense heavyweight concrete can bring to a radiation shielding project. We have published a news article with a detailed business case with information about this particular method.Īdvantages of using MagnaDense as a radiation shielding material Modular high density concrete blocks: Radiation shielded walls are built using blocks made of heavy concrete and MagnaDense.“Sandwich” walls: As the name of this solution indicates it involves a layer of compacted MagnaDense between two (mostly) pre-fabricated walls which act as a lost formwork.Standard heavy concrete walls: Walls made of high density concrete which contains MagnaDense.Ultimately, there are several construction solutions for using the high density aggregate MagnaDense to build a radiation-protected room or bunker to provide the right degree of defence: As a result, MagnaDense concrete gives full protection but uses less space. Contrary, standard concrete typically has a density of up to 2.4 t/m³. Therefore, our customers use MagnaDense as a concrete aggregate in the concrete formulation to achieve densities of up to 4.0 t/m³. Moreover, with a higher density material, you can reduce the radiation faster. How does high density concrete block radiation?Ĭoncrete shielding reduces the intensity of radiation depending on the thickness and density of the concrete structure.
