Concrete structural system

A concrete structural system configured to provide electromagnetic shielding, the concrete structural system comprising:

• a first structural component, the first structural component comprising a precast concrete panel including a first end, a second end opposite the first end, a first length extending between the first and second ends, a first height, and a first interlocking portion at the first end and extending along at least a portion of the first height;
• a second structural component, the second structural component comprising concrete and further comprising a third end, a second height, and a second interlocking portion at the third end and extending along at least a portion of the second height;
• a plurality of plates secured to and extending along the first and second interlocking portions and surrounding surfaces of the first and second interlocking portions;
• wherein the first structural component and the second structural component are each comprised of a conductive concrete composition;
• and
• wherein the first interlocking portion of the first structural component and the second interlocking portion of the second structural component are configured to interlock with one another to minimize leakage of electromagnetic waves between the first end of the first structural component and the third end of the second structural component.
