If for normal concrete the density is 2400 kg/cc. m, for the light - from a minimum of 350 through 800 to 1920 kg/cc. m, for the high-density one it is from 3360 to 3840 kg/cc. м.
In addition to the main ingredients in it there are high-density fillers - barite, limonite, magnetite. It is also achieved by reducing the voids and increasing the cement content.
