High density concrete and concrete blocks are
a relatively new entry into the radiation shielding product line. The
poured concrete and interlocking blocks can offer a cost effective
material when compared to lead for linear accelerator vaults and other
applications requiring heavy lead thickness. Depending upon the
shielding requirement, HD concrete alone or in combination with lead
brick can offer cost savings with identical shielding characteristics.
HD concrete can be poured, pumped or
conveyed during initial construction of a vault. Three types of block
are also available including interlocking chevron-type, solid
rectangular type and 3 core HD masonry. The latter two require matching
density HD grout. A variety of block sizes are available depending upon
the style selected. All 3 styles are available in 250 PCF/4.01 GCC and
300 PCF / 4.81 GCC. Custom sizes and densities are available upon order.
a-fabco can arrange for installation or
you may choose to work with the general contractor or the masonry
contractor on your job which may
save money on the total project.
The interlocking chevron blocks are
pictured in the job to the right. HD blocks were used not only in the
walls, but a steel beam ceiling was constructed and the block was used
for overhead protection as well.
