What are the most cost-effective construction methods to research and consider for building a 75' (23m) habitable structure that will stand safely for at least 500 years in the absence of structural maintenance? What aesthetic considerations should be made before blighting the earth with such a durable structure?The structure will be on flat wooded acreage in western Pennsylvania, USA, with construction beginning within the next three years at the earliest. Ideally, it would be designed in such a way as to permit the building of one story at a time, as funding is available, but I can put off the project for several more years if it makes better financial sense to do so. Initial usage will be roughly equivalent to a hunting cabin and over-built hunting blind, eventual usage will be as a residential home. Natural lighting is important.I anticipate eventually assembling some kind of knowledge archive on the site, so any ideas on that front would be appreciated, as well.
Concrete and rebar, like everything else
>>2227708I've done some work with concrete and rebar decks but haven't done much with tall walls or multi-story structures. Any pointers on where to read about this? What do I need to do to not have to replace the concrete in 50 years?
>>2227721Though it would be really cool, I have a suspicion that quarrying and transporting the stone for a 75' megalithic structure would probably not be cost-effective. It could be worth checking into cyclopean architecture, however, depending on what kind of quarries are nearby and what kind of friends I can make locally.
>>2227707Holy Jesus kid! Stop eating your mom's meds.
>>2227707>most cost-effective construction methods>for at least 500 yearsstones make the best building material, only problem is theyre expensive. you can get around some costs by doing things yourself by hand but that can become time consuming.if i were you i would start digging out the foundation, see what your hole gets youif you find alot of large stones you can probably reduce costs by using your own stones instead of buying them.if you find alot of clay (common in pa) you can make your own bricks. theyre not as longlasting as stone but you can take steps to prevent their deterioration.brick making is easier than you might think, it just takes commitment. you can look up "brick making" on youtube.for cheap construction you can make a significant part of the base concrete, to prevent deterioration you can build stone/brick around the concrete pillar as well as a roof/gutter/water directing system. if rain doesnt touch the concrete you wont see the melting/cracking that usually comes with concrete buildings.
>>2227707Stainless steel rebar.
>>2227818Now your talking!Six or 7 story concrete tower with a 25' diameter base, walls 4' thick at ground level with stainless rebar welded. Mix carbon fiber into the concrete.first floor is 17' on the inside diameter.Use half of that for an elevatorThe pilings for the foundation would go maybe 40' down.Get your buddies to help on the weekends and you could do it for about 15,000.

>>2227707DIE MONOLITH UNFREN
Use lots and lots of concrete. So much so that it cannot be dynamited. Stone can be chiseled away and repurposed but concrete will never be worthwhile to remove. Hitler's AA towers are still standing for this very reason.
>>2227707stack rock, build phalicly, and most importantly, build taller than the bushes.
drunk retard here. will concrete and rebar last anywhere near as long as huge sandstone blocks?
>>2227988No of course not. Concrete will eventually crack. Then water gets in, freezes, it cracks more, the water reaches the rebar, it starts to rust. Why do you think concrete road infrastructure needs so much maintenance? Buildings experience different stresses than roads of course but if you don't actively maintain it your building collapses like that one in Florida or every single parking garage in the next 30 years.
>>2227715>What do I need to do to not have to replace the concrete in 50 years?not make it from todays shitty concrete
>>2227988>>2227994Oh, and I'll just add on that sandstone holds up a lot better in the Sahara desert than it does in fucking Pennsylvania. It barely ever rains in the desert. In Pennsylvania it rains significantly more and there's more water vapor generally in the air. While it gets cold in the desert little if any water condenses out. In PA water will condense out and freeze which will crack sandstone just as well as concrete. The weather of sandstone blocks would be faster so in that sense concrete is a better pick but is still not future proof.

I've thought of a similar idea- You need land with stone already available. I have looked at old defunct stone quarries for sale. You can find some, but not many. The trick stone. You can get a giant wet saw and face the stone into bricks. But like the other commenter 5hat becomes time consuming. Stone brick walls finished with a sort of durable lime plaster. Lime plaster cures and gets harder over time, and with each watering.
>>2228506To add; think of things you can build with old growth timber. Some of the oldest standing buildings are built from timber. If maintained can last hundreds of years.Incorporate a history of yourself and your family into the structure to ensure a place your lineage can improve/maintain.

>>2227707Brick corn silos with good foundations have been standing for 200.If the roofs had been tin, they'd stand for another 300
You and me have the same dream.You must take inspiration from Europeans. They used stone foundations and stone walls. The key ingredient though is the mortar and cement. You can't use Portland cement. Portland cement will fall apart softer 50-150 years. The Euros used some kinda limestone cement, I'm not sure of the exact ingredients, but this is why their buildings are still being held together 100s of years later.Also, as the other anons have said, don't use rebar. There's going to be lots of factors which decide how long your structure will last. Just don't fuck up the foundation, don't let water get in, and don't use home Depot cement.
>>2227707>Trying to build a wizard tower>doesn't consider using magicwhat a fool
>>2233273>The Euros used some kinda limestone cementi wonder if bags of limestone sold at lowes could be turned into roman concrete. the firing temperature seems easy to achieve. i might have to test it out someday.
>>2227731Well, do you have mineral rights to your land? How deep is bedrock? Are you comfortable firing brick?My advice would be building with long flat bricks in the Roman style fired from clay from your backyard walls about 36" thick at the bottom tapering to 12" at the top, increasing the number of windows as you rise. The structure should be circular in nature, which creates a powerful compressive structure that resists wind from any direction. This lets you quarry materials locally without splitting stone, but firing bricks can be pretty tricky, so read up. Also, the foundation needs to go down to bedrock. No excuses. No rebar or iron whatsoever if you want it to last 500.
>>2234429>Well, do you have mineral rights to your land?Yes, with an active gas lease.>How deep is bedrock? ~10ft in most places, going to have some proper sampling done before I finalize the exact monument placement or do anything else.>Are you comfortable firing brick?Not yet, but I'm willing to give it a go. I've been wanting a kiln eventually anyway for other projects so I'll probably go commercial rather than /diy/ for the brick oven if the /diy/ brick route ends up being otherwise practical. >long flat bricks in the Roman style>about 36" thick at the bottom tapering to 12" at the top, increasing the number of windows as you rise>firing bricks can be pretty trickyDo you have any reading material suggestions supporting these points? I've been looking through pictures of old block structures and have been trying to learn about brickmaking.
how will anon make floors/stairs
>>2235800Haven't you ever built a tower out of brown bricks in Minecrap? Just have a spiral stairway or two going up the inside of the exterior wall. Admittedly, this might be a bit more difficult if you use plain concrete for longevity (since you can't just cantilever the stairs straight out of the wall), but it certainly isn't impossible.
>>2235800(And, as for floors, where did OP say he wanted multiple floors? Maybe it's just an ordinary 1500-ft^2 house that happens to be embedded within a 75-ft-tall hollow pyramid of concrete.)
actually, steel is out of the question, but that doesnt mean no metal at all.anon can use nice aluminum stairsthey might wear down a little with use though..so he can have a ladder too, so he doesnt use the stairs too much
>>2235800Honestly I'll probably be content with letting the floors and stairs go before the 500 year mark and make them out of wood. There are ways to build vaults, support floors, and build stairs with masonry but I'm not sure if that will be worthwhile with how small of a footprint this structure is likely to have. I would like to learn more about that kind of masonry, however, and will probably do some relevant reading before breaking ground.

>>2240331No need to use granite for the entire structure. Just place the granite on the bottom of the building -- we call these water tables. When the water runs off the roof, it hits the ground and splashes into the granite, which is hard an durable. The stones above the granite can be limestone or whatever. Just make sure the limestone doesn't come into contact with water and you're solid. Granite is so heavy, but if I had access to it, I'd build the structure entirely out of that. I'm just saying though, you don't need to if you want a structure to last. Even concrete will last for 100s of years if you do a few simple things to it. There's shit loads of different mixtures you can use that will provide a long lasting and durable structure.

Ideal conditions for degrading just about every man made structure.The only monoliths that have effectively stood the tests of time in such conditions similar are aztec pyramids/temples. But with snow and cold temperatures? It could work due to the high incline of their pyramids. Granite would work...expensive though. Slate would be too, shale wouldn't last. Bluestone perhaps would be your cheapest alternative. Concrete would not last, but perhaps stacked stones and mortar. There are miles of stacked stone walls in Connecticut/new england, some are foundations of old houses too. In any case, dig to bedrock, especially since it's not too deep. that would make it last as long as possible and it wouldn't frost heave any hidden stones under the foundation.>>2242215This is what they did in new england, only replace the "quarry" and "stone blocks" with "farmland and frost heaved stones".

>>2242622Concrete is reconstituted stone...which just proves ever further that stone is better (for longevity). The problem with concrete vs stone is that stone is naturally created as a coherent piece of molten minerals/metals. Concrete is incoherent, just a bunch of rocks glued together with a chemical reaction. Even if it were low permeable to water it would still crack and succumb to itself. The "better solution" is to just remelt the rocks back together instead of gluing them.With cut stones...they just sit on each other. They are as stable as the foundation they're put on.

>>2271776As pointed out, it's more expensive.As a complicating factor, we only (relatively) recently discovered the fact that putting steel into concrete fucks it up after 50-80 years. But now there's huge industry behind doing exactly that, and industries that big are generally slow to change.As a further complicating factor...what are you supposed to replace it with? Any metal corrosion-resistant enough to last "indefinitely" is going to be horrendously expensive, and would only get even more expensive as millions of tons of it gets put into buildings and roads. The alloying materials to make steel itself more resistant to rust are, themselves, expensive. Polymers might work, but aren't as strong, and there may be thermal or moisture expansion issues, depending on the polymer. Glass fiber looks almost ideal on paper, since it's cheap, doesn't corrode, and is a good match for concrete in terms of thermal/moisture issues. But it may not handle shock loads from seismic effects very well.

>>2240220not at 75ft tall. the point of rebar reinforcement is to steady the structure against tension - concrete is great at holding itself up, but as soon as anything starts shifting or swaying it tends to crack. rebar is there to support tension on the structure, which would be created by the strong winds which are present above a treeline

To be completely honest, I think a tower is the worst possible structure if you're talking about longevity. Lateral stress from rain, storms, erosion and so on will only need to bring it out of balance by a few degrees and it will crack, no matter if you use concrete with rebar, quarry stones or whatever you can come up with. If you really want something that will endure centuries you might want to look at a structure with a footprint at least 3 times the size of its peak as well as a rough height-to-diameter ratio of 2:1 at max.

I suggest building a 45 degree angled pyramidal structure out of monocrystalline silicon, or out of cast monocrystalline silicon blocks. If you have the budget and wherewithal, silicon carbide would represent an excellent upgrade path for even better durability and stability.Monocrystalline Silicon, is among the most stable and cheap materials known to man.It can be purchased in cast boules or blocks at modest prices, particularly when bought in bulk.it is lighter and stronger than virtually all mixed mineral materials. It is extremely thermally stable, and does not react readily with anything found in significant quantities in the environment, it is nonporous and impervious to water infiltration and ice cracking, it provides no nutrition and so is not attacked by lichens or other lithotrophs. It is readily mass produced, and has a melting point of 1400 degrees C, and a thermal expansion that is well matched to its naturally occuring passivating oxide layer, as well as the oxide having better chemical resistance and higher heat tolerance than the silicon. Further, the silicon oxide layer fills any cracks that could form or be made by future chiseling, wear, rock strikes or vehicle strikes, etc. And prevents further oxidation within those cracks as well as sealing them against further erosion by providing a hard, heat, chemical, moisture, biology and impact resistant surface layer. The cost of such a project would probably be less than a comparably durable maintenance free structure made of any other material.

Currently leaning towards using as much brick as possible on top of a water table of yet-undetermined materials.
>>2296643>on top of a water table of yet-undetermined materialsFor the practice mini-towers I'm thinking of using free/cheap 55 gallon drums with the ends cut off as concrete form tubes for my foundation and water table.
