| | According to new research the pyramids were actually made by casting the stones from a concrete-like mix of limestone, lime, and diatomaceous earth that was mixed so perfectly and consistently that no scientist even suspected it until recently. There are still some details to be worked out such as how they actually made all the inner chambers and how they hoisted all that mix to the top to pour in the capstone, but the atomic science doesn't lie, those stones are unlike any limestone that can be found anywhere in nature. Yet another example of how you'll have to unlearn what you "learned" in school! |

Cool stuff. I have often wondered where the concept of "concrete" comes from... I wondered how the relationship between calcium, Limestone and gravel (rock) first became known and popular. Last Thursday we placed and finished 15 cubic metres of concrete slabs, and I would've liked to have the fellow who designed the stuff there to help.

So they poured it in, huh? Strange, isn't it? People have been puzzling for a long time how they made those pyramids. There were theories about long sand ramps that go in a straight line or "hug" the pyramid in a spiral fashion. All in all, it involved people hauling large blocks of stones all the way up there. If what you said was true, then the greatness of the Egyptian empire will diminish. Hah! Who would've thought they'd take the easy way out  I do, however, remember reading a relatively recent article about archaeologists uncovering a mass grave of people "near" the pyramids ("near" could go up to as far as miles away) who showed symptoms of vertebrae deformities. Apparently, they have been "heavy at work" before they died, further supporting the theories about "great manual labor that lasted for years on end." Too bad I can't support my claims with links. It was from a newspaper eight or more years ago. Oh well, y'know, as "writer" Erich von Daniken once wrote, the architectural marvels of the world, Egyptian and Aztec pyramids, the Nazca "airstrip", Greek shrines and temples, menhirs, dolmen and stone circles (henges) all make perfect sense if you think of them as the results of the hands of giants (or aliens, depending on which mood he's in)

Ha ha, it figures, but I also thought we would of found some left over limestone mix or some old pot with a mix of the cement in it by now. I mean, they would of had to have tools to pour the blocks in place or something, shouldn't there be something of that nature at the building site or somewhere? Maybe we have and just didn't connect it at the time. You know the person that came across that is really annoyed right now, haha.

Well not all pyramids are created using a mixture of limestone, clay, lime, and water. Only the outer part's which confused scientists for years how could they be so massive and than again so precise. Also what is interesting is the fact that this new mixture is not same mixture as we use for concrete now. I looked at it, and find it strange, so i kept reading article until the end. It looks like that this mixture they were using is much better than concrete in terms of production. Looks like old Egyptians thought us something new: QUOTE "The basic raw materials used for this early form of concrete-limestone, lime, and diatomaceous earth-can be found virtually anywhere in the world," he adds. "Replicating this method of construction would be cost effective, long lasting, and much more environmentally friendly than the current building material of choice: Portland cement that alone pumps roughly 6 billion tons of CO2 annually into the atmosphere when it's manufactured." Hey, i might try this mixture when building me own house

Well, seems the egyptians were geniuses  . They're even teaching us stuff long after they're gone. The cement companies aren't going to be happy about this, but at least it's cheap and healthy.

I'm sure gonna pop a question to my professor about this mixture. maybe they are already researching compression and tension stress values on these materials. dunno

Reminds me of a show I saw once on TV where a guy (Hollywood actor - can't remember his name) built his house from used tires. He would pack them with dirt so full he had to cram it in with a sledge hammer. By the time he was done the tire sidewalls were starting to bulge. These would be stacked and staggered like bricks and the gaps packed with more dirt. I guess since the walls were so thick and packed with dirt the place was always nice and cool even in the summer sun. He built another one from beer and pop cans using the same method. Pack with dirt, stack and fill the gaps. There was no mention of building permits or code or anything so I'm wondering if he had his house inspected. Hey, that would probably be fire proof also. Bonus. Wouldn't want to clean the place though, might be sweeping the floor for a while. Actually I think he had tile floors or something like that. It's been a while since I saw that so it's a little foggy.

My cousin thought that. ( Now before I finish lets just say my cousin thinks he knows everything and when he does he sticks to it no matter what you say! ) They found a bunch of random stones all perfectly shaped the same and the just started stacking them! Yea I know it is a very stupid theory. Btu he still thinks it is true.

Could you please tell me where you found this info, watermonkey?  I'm interested in the Egyptians, and had until now seen and believed the traditional idea: the Egyptians had laborers and worked them half to death to break up stones into a rectangular shape. This idea of making the stones for the pyramid is well...unheard of (at least for me  ) until now.

If this mixture is really practical, hopefully people will switch to that instead of what they've been using. I'd buy it in a heartbeat. Unfortunately, the formula died with it's creators. I'd sure like to see some studies done using only materials available to ancient egyptians to see how closely we can duplicate it. and no, I don't think it's alien technology, mankind has been doing the impossible for a long time. It's just easier if no one tells you it's impossible.

Actually you do NOT have to relearn what you learned in school, just expand it. I looked up the actual article from http://evomech7.blogspot.com/2006/12/great...ing-blocks.html and found out that most of the blocks were quarried and moved from other sites, but others were not. The article states that it would be impossible to cast the entire pyramids due to lack of fuel to heat it. Foundations both then and now are much more stable and level when poured. The interesting thing to me wasn't that they have poured parts, it's that their concrete is so much better than the Portland cement that we use today. I'd like to know how they did that. Here is most of the actual article from that website. The longstanding belief is that the pyramids were constructed with limestone blocks that were cut to shape in nearby quarries using copper tools, transported to the pyramid sites, hauled up ramps and hoisted in place with the help of wedges and levers. Barsoum argues that although indeed the majority of the stones were carved and hoisted into place, crucial parts were not. The ancient builders cast the blocks of the outer and inner casings and, most likely, the upper parts of the pyramids using a limestone concrete, called a geopolymer.
To arrive at his findings, Barsoum, an Egypt native, and co-workers analyzed more than 1,000 micrographs, chemical analyses and other materials over three years. Barsoum, whose interest in the pyramids and geopolymers was piqued five years ago when he heard theories about the construction of the pyramids, says that to construct them with only cast stone builders would have needed an unattainable amount of wood and fuel to heat lime to 900 degrees Celsius.
Barsoum's findings provide long-sought answers to some of the questions about how the pyramids were constructed and with such precision. It puts to rest the question of how steep ramps could have extended to the summit of the pyramids; builders could cast blocks on site, without having to transport stones great distances. By using cast blocks, builders were able to level the pyramids' bases to within an inch. Finally, builders were able to maintain precisely the angles of the pyramids so that the four planes of each arrived at a peak.
Although these findings answer some of the questions about the pyramids, Barsoum says the mystery of how they were built is far from solved. For example, he has been unable to determine how granite beams - spanning kings' chambers and weighing as much as 70 tons each - were cut with nothing harder than copper and hauled in place.
The type of concrete pyramid builders used could reduce pollution and outlast Portland cement, the most common type of modern cement. Portland cement injects a large amount of the world's carbon dioxide into the atmosphere and has a lifespan of about 150 years. If widely used, a geopolymer such as the one used in the construction of the pyramids can reduce that amount of pollution by 90 percent and last much longer. The raw materials used to produce the concrete used in the pyramids - lime, limestone and diatomaceous earth - can be found worldwide and is affordable enough to be an important construction material for developing countries, Barsoum said.

Everything about their entire cutlure was super hardcore. The greeks on the other hand were supreme fail. They believed that two otters could, and very often did. Kill crocodiles. Apparently they thought that they wrapped themselves around the croc's mouth and the other went for the eyes. Cos crocs apparently are supposed to have immense pressure to be able to push down their jaws. But opening them is a different matter. An elastic band is enought to restrain it. Anyway I'm rambling I watched on brainiac history abuse quite a while ago.. That the best way to have made the pyramids wouldnt have been to use slaves, but to treat your employees VERY well. It's proven people work better when theyre being treated than punished. I guess they never thought of this! I reckon the incredibly intricate interior was made from the same material as the outer layer. If they fashioned this material and it worked so well why not use it again? What do these specialists assume the interior is made out of anyway?? How did they fill the big blocks with all this stuff in it? Im so confused D:
