Study on Preparation and Performance of Radiation Shielding Aggregate Made from Sludge with High Content of Barium

Article Preview

Aggregate is the main contribution to shield the radiation in the radiation shielding concrete. Based on the fact that the heavy element barium has excellent γ-rays shielding function, sludge with the high content of barium has been made into aggregate with low dissolution rate and high strength by calcination at high temperature; the existing forms of element barium after it was melted inside the aggregate have been analyzed by using XRD and SEM techniques; the linear attenuation coefficients have been measured among the functional aggregates, basalt and barite. The results have showed that the radiation shielding capacity of functional aggregate has been improved substantially compared with the basalt, however, it is equal to barite.
