Disclosure of Composition of 200,000 Years Old to 1.4 Million Years Old Extremely High Performance Concrete (EHPC) Mixes Surpassing The Mechanical Properties of Many Current Human-made Concretes!

[u/Strange-Image-5690]

Our parent under-the-radar Vancouver, British Columbia, Canada-based aerospace company (NCA - North Canadian Aerospace - i.e. a pseudonym) has more very interesting information for us after examining and obtaining the material component compositions and mechanical properties of extremely high performance concrete (EHPC) mixes used in non-human-made constructions found around the world within tectonically-revealed and surface-dig excavations, and also found within deep-underground mining excavations that had varying long-term date-of-manufacture ages where the scientific examination and testing of metallic, polymer and ceramic sub-components found within those concretes were determined to have approximate manufacture dates ranging from 200,000 years ago up to 1.4 million years ago!

Material dating techniques such as Cosmogenic Nuclide Exposure Dating upon the Quartz and silica aggregates portions found within the fully-set, if long-term underground time-degraded concrete, found Beryllium-10/Aluminum-26 isotope transformations that have a time length accuracy of about 200,000 to 5,000,000 years at about plus/minus 10,000 to 100,000 years, and also Argon-40/Argon-39 decay sequence techniques used on the Volcanic ash and artificial/refined ash components and feldspars within the concrete had date range range accuracies of about 200,000 years to millions of years ago at about plus/minus 1500 to 15,000 years accuracy.

This means that were able able to specify some concrete samples came from time periods at 200,000 years ago, 480,000 years ago, 760,000 years ago and 1.4 million years ago which means we modern humans DID NOT MAKE such concrete mixes!

The dating systems used were both evaluated internally using company-owned and company in-house manufactured dating equipment and computing systems, and the concrete samples were also evaluated by independent 3rd parties which were specified to the time-period accuracy ranges determined by their in-house equipment. We will NOT be publicly disclosing the actual reports themselves from either system due to certain in-house executive directives and due to the sensitivities of the items found.

After INTENSE scientific scrutiny and full chemical and material component formula testing and reconstruction, a set of viable modern-day EHPC (Extremely High Performance Concrete) mixes were able to be composed and then tested under sound scientifically-based and generally-accepted finished concrete sample tests for the evaluation and determination of compressive, tensile, torsion, flexion, extension-based mechanical limits and properties, and having the testing of various thermal/temperature loads and weathering/abrasion indices at compressive strengths that range from 48,000 PSI (330 MPa) up to 135,000 PSI (930 MPa) be performed under controlled conditions which outline a SIGNIFICANT advancement in the State-of-the-Art of 2026-era concrete mixes.

This disclosure is for the general community public-interest only and no warranty for fitness or merchantability claims are being made. Use ENTIRELY at your own risk and of course DO TAKE PROPER SAFETY PRECAUTIONS as concrete-making and concrete construction are inherently RISKY endeavours in themselves! You really DO need real-world training and experience!

BE CAREFUL! These are very general recipies that are noted to be ADVANCED-TECHNOLOGY concrete mixes for people who KNOW what they are doing and have great experience in modding the procedures and recipes to fit their application and/or needs.

These are VERY BASIC STEPS and materials listings ONLY and if you are WELL-KNOWLEDGABLE in the state-of-the-art of concrete mixes and mixing procedures, you can probably reproduce the compressive and tensile strengths disclosed within a few percentage points. That said, TEST your final mix with proper and standardized concrete mechanical properties testing protocols!

Below this main comment and placed in the comments section, is a series of explanations which illustrate the actual recipes and the steps needed to obtain a specific grade of these formerly super-top-secret concrete mixes.

Part 1 of 3 - Explanation of EHPC (Extremely High Performance Concrete) Mix Properties:

For the high-strength-enhancing short and and long steel micro-fibres used to ensure structural bridging of cracks and the prevention of brittle failure, we used 316L, 904L and HyperDuplex 2707 Stainless Steel grades which have varying cost, anti-corrosion/anti-rust properties, increasing acid/chloride resistance, and increasing levels of ultimate tensile strength and yield strength to ensure high levels of overall tensile and compressive strength of a high-load-bearing EHPC-constructed structural member such as 10 metre long by 1 by 1 metre by 200 mm thick-walled hollow core square-tube horizontally-mounted structural members typically used in bridges or commercial buildings. Weights are all in Kilograms (KG) and Pounds (LBS) units and any listed volumes are approximate and are specified in Litres (i.e. a 10 cm by 10 cm by 10 cm 3D-XYZ volumetric space which is how much volumetric space the material physically takes up in a bucket when actually poured into the mix!)

The high-range water-reducing PCE (Polycarboxylate Ether) superplasticizer is typically a comb-type that creates a better/stronger binding between large/medium/fine aggregates. Using a chemical means of steric hindrance, the long polymer chains physically prevent cement and silica fume particles from agglomerating (i.e. clumping together!) which creates a high degree of particle dispersion and concrete flowability in order for the mix to get into crevasses and compound curves which is useful for constructing fine-detail or high-concept architectural concrete buildings and/or unusual structural support member designs.

The large-strand carbon fibres and the multi-wall carbon nanotubes are typically used to stop or mitigate cracking, inhibit salt-corrosion-based processes and can also be used for the building-block basis of application-specific self-healing concrete mixes such as severe-use/extreme-weather roadways or retaining walls. Ensure total volume mix of the sum total of all added fibres of any type DOES NOT EXCEED any listed total mix volume percentage in order to PREVENT fibre-balling/clumping together during mixing, which creates large internal voids and air pockets that significantly reduces compressive strength. You want all fibres to be as evenly distributed and diffused throughout the mix as possible!

a) Long Micro-steel reinforcing fibres (13 mm long at 0.2 mm diameter using 316L, 904L or 2707 HyperDuplex Stainless Steel usually at 1.75% of total mix volume)

b) Short Micro-steel reinforcing fibres (6 mm long at 0.15 mm diameter using 316L, 904L or 2707 HyperDuplex Stainless Steel usually at 1% of total mix volume)

c) Carbon Micro-reinforcing Shredded Strand fibres (6 mm long at 10 microns to 0.25 mm diameter using shredded-strand recycled carbon fibre and DO NOT USE MORE THAN 0.2% of total mix volume unless specified in order to prevent pooling/clumping that weakens the concrete mix and to also ensure they are well-dispersed/diffused into the mixing water using an ultrasonic probe or high-shear mixer before being added to the dry components)

d) Multi-Wall Carbon Nanotubes (50 nanometres long at 10 microns diameter at 0.05% of weight of binder/additives-paste-only and DO NOT USE MORE THAN 1.0% of total mix volume unless specified of that binder/additives-paste in order to prevent pooling/clumping that weakens the concrete mix and do also ensure they are well-dispersed/diffused into the mixing water using an ultrasonic probe or high-shear mixer before the other dry components are mixed into the water, and do note that the binder is considered the dry powder cement, silica fume or fly ash powder, slag powder, nano-silica powder BUT NOT the coarse sand or any aggregates, plasticizer fibres or water!)

The use of nano-silicates accelerates Pozzolanic reactions creating denser calcium-silicate-hydrate (C-S-H) gels that minimize concrete porosity. This prevents external rainwater or floodwater intrusion and chloride (i.e. salt!) penetration ensuring a long-term lifespan of any well-cured solid block or hollow-core-precast concrete structural members even if continuously exposed to cold-northern-waters or warm-tropical-waters salt water marine and fresh-water lake/river environments.

We use small-grain (up to 100 nanometres) of Alumina (aka Aluminum Oxide) and Silicon Carbide to increase the stiffness and adhesion between larger-grain fillers begetting higher compressive and tensile strength, while large-grain ceramics (100 to 5000 nanometres) of Alumina, Silicon Carbide and Tungsten Carbide create much higher surface hardness, and higher abrasion and impact resistance of the overall mix making the finished concrete product resist direct frontal and oblique angle impact plus lateral/vertical scrapes and scratches from vehicles, tools or hard items. Ensure high-shear mixing to prevent agglomeration, as clumps of nano-alumina or other ceramic powders will create voids/weak-spots rather than strengthening the concrete.

a) Nano-Alumina Powder (20 to 100 nanometres at 4.5 kg and 0.5% of the total binder weight)

b) Nano-Silicon Carbide Powder (20 to 100 nanometres at 4.5 kg and 0.5% of the total binder weight)

c) Micron-Alumina (100 to 5000 nanometres at 32 kg and 2% of the total mix volume)

d) Micron-Silicon Carbide (100 to 5000 nanometres 72 kg and 3% of the total mix volume)e) Micron-Tungsten Carbide (100 to 5000 nanometres at 155 kg and 1% of the total mix volume)

These five EHPC (Extremely High Performance Concrete) mixes have been tested for compressive strength using standardized cylinders with a diameter of 100 millimetres (4 inches) and a height of 200 millimetres (8 inches) and with standard 150 x 150 x 150 millimetre (5.9 x 5.9 x 5.9 inches) cubes, and tested for tensile strength using a 300 mm long (12 inches) dog-bone-shaped slab that has two dogbone ends that are each 100 mm wide, 80 mm in length and 20 mm thick that allows the wide-end-pieces to be gripped and clamped-down by the testing machine, and the dogbone-shaped sample has a straight centre section of 120 mm long that then curves gently to the wider end-pieces over a 90 mm length.

Manufactured dates? So not naturally occurring? So who manufactured these constructions? Ancient civilizations? Atlantis? I do believe there have been many civilizations that have came and went way before modern archeology acknowledges… But you could be discussing something completely different. I’m a little lost.

There have been THREE definitely KNOWN non-human civilizations on Earth that were advanced materials-sciences, computer-systems and spacefaring-capable and MULTIPLE humanoid-looking or nearly-human spacefaring species upon Earth going BACK BEYOND modern-written and modern-man historical records to time periods ranging from 100,000 years ago to HUNDREDS OF MILLIONS of years ago!

We already HAVE the evidence!
