The material is named in honor of the British engineer, journalist and intelligence officer Jeffrey Pike, the first part names – surname, second concrete.
Pykerite is 4 times stronger than ice, malleable, and has about the same resistance to explosion as concrete. Due to its low thermal conductivity, it melts more slowly than pure ice.
In the early 1940s, Pike proposed building an aircraft carrier out of this material (Project Habakkuk).
Some sources indicate that during the Quebec Conference of 1943, Lord Mountbatten arranged a demonstration of pikerite capabilities for the admirals accompanying Winston Churchill and Franklin D. Roosevelt. Mountbatten brought with him two identical blocks – one made of regular ice, the other made of pykerite. Putting them in half of the room, Mountbatten fired at them one by one from his service pistol. The ice block shattered and shattered, and from the pykerite block, the bullet ricocheted and, tearing the trouser leg of Admiral Ernest King, stuck in the wall.
