As Steven W. sayes, use of blood in mortar is not new. If used, the source for the blood would be slaughterhouses. We have a few in the Midwest.

I am coming late to this and assume that the Patent info is on the last thread, which, it being late, I am not going back to read.

...For the Romans’ grander and more artful structures, as well as their land-based infrastructure requiring more durability, they made cement from a naturally reactive volcanic sand called harena fossicia. For marine structures and those exposed to fresh water, such as bridges, docks, storm drains and aqueducts, they used a volcanic sand called pozzuolana. These two materials probably represent the first large-scale use of a truly cementicious binding agent. Pozzuolana and harena fossicia react chemically with lime and water to hydrate and solidify into a rock-like mass that can be used underwater. The Romans also used these materials to build large structures, such as the Roman Baths, the Pantheon, and the Colosseum, and these structures still stand today. As admixtures, they used animal fat, milk and blood -- materials that reflect very rudimentary methods. On the other hand, in addition to using natural pozzolans, the Romans learned to manufacture two types of artificial pozzolans -- calcined kaolinitic clay and calcined volcanic stones -- which, along with the Romans' spectacular building accomplishments, are evidence of a high level of technical sophistication for that time."

My impression - and somebody else with actual industry background on another thread somewhere posted something similar as was previously posted here - that the use of blood in cement in this time + era would be weird - there are synthetic materials or other things that could / would be used instead - if the purpose was tensile continuity or strength. However, my inference from these things with CEMEX is that the purpose would be something occult ... such as building a chapel of ill repute or satanic worship of something like that.

One of the most interesting thing I find about CEMEX coming into the picture now is that it was in the picture months ago, at the periphery of other things. I can't recall which / what that was, just that it was something that was in the midst of other things and I then made a mental note of their transportation routes, etc.

Thus my belief that this is a worthy digging endeavor with discretion & discernment about what is or may be there ... TBD ;)
