CyBe 3D Printing with Concrete, Owner Provides Details on Printer & Mortar

There seems to be a lot of mistakes in the specs. Perhaps you used mm (millimeter) in places where you meant M (meter)?
As in you built a wall 400 mm (about 16 inches) long?

The specs seem a little iffy, but the numbers came directly from Berry Hendriks via email and on the CyBe website, so we can't confirm them from the sources at hand.

The wall certainly seems longer than 400 mm -- perhaps more like 4 m, though, from the look of it; definitely not 400 m.
