That means the floor slabs upon which apartments sat were made of concrete that was poured around horizontal lengths of rebar, or stout steel rods, that provided critical strength when the concrete cured. The molasses had been warmed to reduce viscosity during transfer, but the warmer material, in addition to the rapidly warming air temperature, must have strained the tank itself. This necessity was met, and a plan for supporting pits with post-tensioning cables to resist the earth pressures was formulated.
