Black concrete from Lapland
Between the 18 massive columns that provide structural support to the different levels of the Tokamak Complex, walls will be made of a special, high-density concrete (3.9 tonnes per cubic metre as compared to 2.5 tonnes for regular concrete). Producing the concrete on-site will require 6,000 tonnes of magnetite gravel that is being shipped from Kiruna, in Swedish Lapland. Inspecting one of the completed walls (out of 18) are Paul Lugardon (BIPS buildings project team) and Benjamin Sar (VFR consortium).
