This paper presents the use of barite as concrete aggregates to block gamma-ray radiation. Two concrete grades fc'25 and fc'35 were prepared. The effect of barite to the attenuation coefficient of samples was studied by replacing coarse aggregate with barite and replacing both coarse and fine aggregates with barite. The results show that ...

The replacement of the natural aggregate with barite in UHPC concrete resulted in a 12.8–21.1% reduction in compressive strength [18,45]. This result is due to the lack of enhancement in the interfacial transition zone between barite and cement paste and the disintegration of barite during the mixing process [45,74].

concrete is universal material and barite powder can be use in cement concrete. Barite (BaSO4) gets its name from its high density, in fact, barite comes from the Greek ''barys'' which means heavy. This is due to value of 4.48 at 26℃ this value is close to that of some iron or lead ores, such as hematite or galena.

Barite, a type of heavy aggregates, is generally used in heavyweight concrete production for against gamma radiation [15]. Heavyweight concrete attenuates both neutron and gamma radiation in neutron research facilities [16]. In addition to heavy elements, neutrons also need shielding materials containing light elements for elastic collisions [17].
