The pyramids may not have been carved. They may have been poured. Joseph Davidovits published this claim in 1979 and spent 40 years backing it with chemistry. The Great Pyramid's core blocks contain traces of organic matter, diatomite, and hydrated calcium silicates — characteristics of cast concrete, not natural limestone. The outer casing stones are chemically different from the bedrock they supposedly came from.
If true, this changes everything. 2.3 million blocks. Average 2.5 tons. Built in 20 years. The math never worked for carving and hauling. It works fine for pouring in place.
These are the actual recipes — six test tiles, same mold, air-cured 28 days, then tested. Phase 2 is Ed's machine (see Leedskalnin Decoded). Phase 3 is sun curing at high temperature to achieve full strength.
Tile A and B are pure science — published formulas, replicated in labs. Tile C and D move into territory where published results exist but fewer labs have tried. E and F are new directions — labeled clearly as such. Nothing is overclaimed.
Davidovits geopolymer formula. The candidate for Great Pyramid core blocks. 40–60 MPa at 28 days air cure.

|---|---|---|
| Crushed limestone / calcium carbonate powder | 10 lb (4.5 kg) | Amazon or garden center |
| Metakaolin | 5.5 oz (160 g) | Amazon "Burgess Optipozz" |
| Washing soda (Na₂CO₃) | 2 oz (60 g) | Arm & Hammer Super Washing Soda |
| Hydrated lime Type S | 3 oz (80 g) | Home Depot |
| Water | ~2 cups (500 mL) | Tap |
Mix: dissolve washing soda + lime in water → add to dry limestone + metakaolin → thick oatmeal consistency → pour → cover with plastic → 28 days shade. Source: Davidovits 1979–2020; PMC 8398852.
Roman concrete. Self-healing. The Pantheon recipe. Gets stronger for millennia. Uses quicklime — the MIT hot-mixing discovery (2023).
| Ingredient | Amount | Source |
|---|---|---|
| Metakaolin (volcanic ash substitute) | 4 lb (1.8 kg) | Amazon "Burgess Optipozz" |
| Quicklime (CaO — NOT hydrated lime) | 2 lb (900 g) | Amazon or farm supply |
| Sand or crushed lava rock | 2 lb (900 g) | Home Depot play sand |
| Sea salt | 2.5 tbsp (40 g) | Grocery store |
| Water | ~2 cups (500 mL) | Tap |
Add water SLOWLY to dry mix. The heat is the feature — lime clasts form, then self-heal cracks for centuries. Source: MIT PNAS 2023.
Standard Portland base + pulse curing (Ed's method). The pulse converts calcite → aragonite (+85% strength). Needs a capacitor discharge unit.
| Ingredient | Amount |
|---|---|
| Portland cement Type I/II | 5 lb |
| Wet oolitic limestone aggregate | 10 lb |
| Water | ~1.5 cups |
Pour tile, leave wet. Apply 200kW capacitor pulses at 500/min for 5 minutes while wet. Let set 28 days. Expected: harder than Portland alone. Verify with XRD for aragonite phase. See Leedskalnin Decoded for full circuit.
