Abstract
Radiation shielding composite material can include basalt fiber and concrete. The basalt fiber can be basalt-boron fiber, basalt-gadolinium fiber, basalt-boron gadolinium fiber, or a combination thereof. The concentration can be up to about 60 kilograms per cubic meter and, in some embodiments, range from about 60 kilograms per cubic meter to about 20 kilograms per cubic meter. The basalt fiber can be formed from a basalt melt that includes up to about 20% of boron oxide, up to about 20% of gadolinium oxide, and up to about 10% of boron oxide and about 10% of gadolinium oxide. The concrete can be ordinary concrete or heavy (i.e., barite) concrete.
Claims21
1-20. (canceled)
A method for forming a radiation shielding composite material comprising:
- mixing radiation absorbing compounds with basalt to form a mixture with the radiation absorbing compounds being selected from the group consisting of borates, boron compounds, and gadolinium compounds;
- melting the mixture in a melting chamber through induction heating to produce a melted mixture;
- forming the melted mixture into basalt fibers;
- finishing the basalt fibers;
- and
- combining the basalt fibers with a matrix material to form radiation shielding material.
The method of claim 22, wherein the forming step forms basalt fibers selected from the group consisting of basalt-boron fibers, basalt-gadolinium fibers, and basalt-boron gadolinium fibers.
