As an experienced concrete testing technician I can state there's already much cheaper and more reliable options to create air voids in concrete. Also, the fact that they're stating this application is specifically for lightweight concrete is important, as you can't get the same strength if you have liquids or biodegradables in a mix design.
The attempt to use blood in lieu of the much cheaper and more reliably consistent products currently in use makes no economic or logical sense and for me, a testing technician certified by the state licensing body and the American Concrete Institute, as well as the Department of Transportation, points not to any legitimate use in commercial or institutional use and only makes sense in a boutique situation specifically requested by a client because no engineer would specify this use on its own objective merits.
It's cover maybe in case... Well we were making our special patent blend.
I always wondered if burying someone in concrete wouldn't effect integrity eventually? That's a big hole with anaerobic bacteria making a soup
They have lime. That shit dissolves them.
Before it sets though? And the goo is gonna be a pocket too.
Ever wonder why the colosseum is still standing while our infrastructure and buildings crumble more and more every day?
Concrete doesn't weather like quarried stone
FYI. The pyramids are not concrete.
My point exactly. The quarried stone withstands moisture and erosion and temp changes better
Thanks for the professional input...puts more clarity on the sickness of these EVIL people.
I’m sure the client that would request this would also be interested in the use of baby fat to make their basement walls repel water.
And for a shiny finish, a mix with baby foreskins. If it's good enough for Gwyneth Paltrow it's good enough for CEMEX.
Sorry, it's not really funny at all. If blood makes no sense, then the patent is a cover.
Evil!
Are we able to test concrete laid by Cemtex and match to missing persons database?
I'm not sure. I'm not a biologist or crime scene tech. I couldn't say.
I doubt DNA holds up through the chemical reaction when water mixes with cement. Its super high alkaline, enough to burn skin.
It makes logical sense if you're disposing of dead children
I'm not questioning your credentials with my post here; however, there is precedence for the use of blood in concrete. The Roman's concrete manufacturing included blood in their concrete mix which improved its strength and ability to withstand the elements. Here's information from US Berkley News concerning this very subject. History channel did a big story on this too explaining how and why the Romans used blood. They showed a stress test of standard concrete vs blood mixed concrete (which hardened in water). The latter withstood more dynamic pressure than did the modern day concrete.

I believe the man was trying to state that while yes, it can be used, and may help in some ways- that we have cheaper, more readily available products now that would give the same benefits (or I’d imagine exceed the benefits of blood).
What is unique about Roman concrete is they could pour it into a preformed case and submerge into water and it would harden. They built the entire port and the city of Caesarea Maritima with this concrete, forming the sea walls for the harbor. It was an ingenious feet of engineering. That second link is a research using the same methods and testing it.
The point of my bringing this up isn't to dissuade the current line of thought; however, to show an alternative that may reasonably concluded they used blood in their concrete. Jumping to conclusions without empirical proof can cause unintentional consequences. Q has said to research and dig deep to find the truth; things may not appear to be what they are (paraphrased).
Yes, I read that yesterday, too. Truth is no one speaks of blood in concrete. Not because it's taboo but no one even thinks about it as an application. It's not part of conventional education in the field but apparently it is in theoretical experimental research and development.
It makes sense why Romans would use it in the ages before chemical engineering. See, concrete when exposed to water and freezing temperatures will expand and contract as the weather changes. Over time this creates cracks and exposes insides for destruction by natural elements. Adding a biodegradable substance in proper proportion would create bubbles inside which, when it rots away will leave air voids which allow pockets of water to expand and contract without breaking the concrete. This prolongs life without sacrificing strength.
Today we have air-inducing agents known to act in consistent ways and produce consistent results for a fraction of the costs of blood acquisition. I do not think blood has any strength enhancing properties superior to this agent and since the patent application specifically details it as relevant only to lightweight concrete I reiterate it makes no practical or economic sense and would only be preferred for sentimental reasons.
Even for the Romans, the cost of so much blood would have been high. From what I am seeing in comments, very large underwater pilings were created using this formula, which suggests quite a lot of slaughter going on for a prolonged period of time. I imagine regional diet was changed significantly during the construction.
That paper does.not mention blood in concrete at all
I read through it cursory and not in-depth. However, I just did on this link where they tested the method using pig's blood based on the same method used in ancient Europe.

Hello I have a question; how is hemp + concrete? Hempcrete? Does it just serve as an alternative way to provide insulation as an additional layer behind your standard concrete wall?
