A Dual-Use technology is one that has both civilian and military applica tions. Enriching uranium is a good exam ple. A country may legitimately do so to fuel power stations. Or it may do so illegiti mately to arm undeclared nuclear weap ons. Few, however, would think of con crete as a dual-use technology. But it can be.
