    How did the Egyptians build the pyramids?

    Lime is an important chemical required in the construction industry, and can be made by burning pulverised limestone in a lime kiln. One of the best fuels to use for the kiln is wheat straw, which burns hotter than even red oak. Straw is therefore a vital commodity, and one that was cruelly...

    Haul a block hey? As an engineer please explain how this would happen.

    How did the Egyptians build the pyramids?

    What do you mean lost technology? We have an excellent understanding as to what they did because we do it today and it isn’t complicated. I asked if “blocks” was a confirmed understanding, after which you the expressed interest in this theory!? Remember? 40 men with 50-60kg of crushed...

    How did the Egyptians build the pyramids?

    What are you on about? This was @shunyadragon source??? Until recently it was hard for geologists to distinguish between natural limestone and the kind that would have been made by reconstituting liquefied lime. But according to Professor Gilles Hug, of the French National Aerospace Research...

    How did the Egyptians build the pyramids?

    Always read a source for yourself. @shunyadragon conveniently left out the following from his source. Lime from fireplace ash and salt were mixed in with it. The water evaporated, leaving a moist, clay-like mixture. This wet “concrete” would have been carried to the site and packed into wooden...

    How did the Egyptians build the pyramids?

    You are embarrassing yourself now. Reconstituted limestone is a building material that is used in preference to natural limestone!

    How did the Egyptians build the pyramids?

    Are you done? I didn’t invent reconstituted limestone, so go be a good little engineer and do some research before you accuse me of anything. You are not too old to learn, and if you are, then why are you here?

    How did the Egyptians build the pyramids?

    Do a simple Google search. https://www.houseandhomeideas.co.uk/blog/why-reconstituted-limestone-blocks-should-be-used-to-build-a-house/ What is your point? Mine is natural and reconstituted limestone are very comparable as building material, but the latter is far, far more practical.

    You are not an engineer, which is the expertise required to understand construction materials.

    How did the Egyptians build the pyramids?

    Do the pyramid stones have a granular surface or not???

    How did the Egyptians build the pyramids?

    The process is simple. Crush the limestone, mix with cement (which is limestone and clay) and water, and then cast into a mould. If using a copper mould, a “natural” granular appearance could come through given it is a soft metal.

    How did the Egyptians build the pyramids?

    First of all, concrete and cement are completely different. Concrete is the mixing of sand and cement, which is very important. Cement contains limestone and clay. Secondly, reconstituted limestone contains cement, LIME, and limestone. ZERO concrete! Lime is CaO, a completely different...

    You are not engaging with what I am saying.

    How did the Egyptians build the pyramids?

    Described by who? Source? For arguments sake, what would be the difference between natural and reconstituted limestone?

    How did the Egyptians build the pyramids?

    You keep referring to concrete. I am talking about reconstituted limestone.

    How did the Egyptians build the pyramids?

    I like to think my sense is mostly common.

    How did the Egyptians build the pyramids?

    Reconstituted limestone is not concrete.

    How did the Egyptians build the pyramids?

    Simple examples would be helpful. Wouldn’t both undergo similar chemical weathering?

    How did the Egyptians build the pyramids?

    I never underestimate the predictability of human stupidity. I also don’t overestimate human practicality, especially those living in times without the wheel.

    How did the Egyptians build the pyramids?

    Were the stones pulled off? Pushed off? Lifted off?
