Store the concrete powder mix in a heated garage or other warm area until use and mix it with hot water when you are ready. Allow the concrete to stiffen after it has been poured and then cover it with insulated blankets to keep it warm or keep the tent up and the space heater running overnight.
A plankowner (also referred to a plank owner and sometimes a plank holder) is an individual who was a member of the crew of a United States Navy ship or United States Coast Guard cutter when that ship was placed in commission. Originally, this term applied only to crew members that were present at the ship's first commissioning.
DEPARTMENT OF THE NAVY -- NAVAL HISTORICAL CENTER. 901 M STREET SE -- WASHINGTON NAVY YARD. WASHINGTON DC 20374-5060. A plank owner is an individual who was a member of the crew of a ship when that ship was placed in commission. In earlier years, this applied to a first commissioning; since then, it has often been applied to one who was part of a recommissioning crew as well. Plank owner is not an official Navy term, and has consequently been variously defined by different Navy units.
