to the techniques of this invention while fig2 a to 2 c illustrate sections of structure wall blocks 200 a and 200 b aac blocks are typically formed by first preparing a slurry of the aac mixture and placing same into current industry standard large mold measuring approximately 4 u2032 wide by 24 u2033 deep and 20 u2032 long after the slurry sets the form may be lifted out of the tray and cut into the desired sizes industry standard panels are always steel reinforced and sized 2 u2032 wide by u2212 8 u2033 thick and when used for walls are 8 u2032 long for vertical height most blocks are usually 8 u2033 wide by 8 u2033 tall u00d7 24 u2033 long with only one usa plant manufacturing a jumbo block of 2 u2032 u00d7 4 u2032 u00d7 8 u2033 the system hereof shows manufacturing modifications of 8 u2033 u00d7 16 u2033 for top block which is coordinated with wall block of industry standard 2 u2032 u00d7 4 u2032 but new dimensional length of 82 u2033 which requires modifying mold length by additional 6 u2033 from the prior art so three lengths of 82 u2033 wall block as well as coordinated casing block can be manufactured without waste accordingly one preferred size is wall block 200 b having an elongated dimension of standard pre hung doors with only jambs to slip flush into invention 39 s.
