Thermoconcrete
- Concrete-like building material in common use by the Federation in the 23rd century (DIS Novel: Desperate Hours; TOS: "The Devil in the Dark"; VAN Short Story: "The Stars Look Down")
- Name assumedly derived from the substance setting under heat rather than over time
- Used in the construction of emergency shelters (TOS: "The Devil in the Dark")
- Sometimes used in situations where concrete would be unsufficiently strong
- e.g., 2.4 km pylons of duranium-reinforced thermoconcrete used to support Arcadia Explorer mining platform (DIS Novel: Desperate Hours)
