Duration: Concrete is made instantly.
note atleast 100 water is needed however ALL the water loaded will be used and the Max button wants 500 water, you have to type in the 100. Teppy was in a particularly evil mode when he coded this.
Uses:
Concrete might be used to upgrade various buildings, like distaffs. Reports still coming in.
