Bariblock ensures higher nominal density with reduced thickness
Compared to traditional mixtures, the use of an inert material with a high specific weight such as Barite (BaSO4) in the mix-design ensures that the finished product has a greater volumetric mass.
Each material, depending on its atomic number and density, has attenuation capabilities with respect to radiation. The question is: how thick does a generic material have to be in order to lower the radiation energy level to tolerable doses for man?
Bariblock®, being composed of barite concrete, is a valid alternative to traditional solutions, as its thickness lies between the heavy and polluting lead and the light and bulky traditional concrete.
Here is a quick comparison of materials based on the theoretical use:
