Concrete

Concrete was a construction material, often composed of cement, rock aggregates and water.
In 2268, when speaking with Jojo Krako, Montgomery Scott attempted to use Iotian slang and threatened to give Krako "concrete galoshes"; Krako understood the meaning but corrected the phrase to "cement overshoes". ()
