Concrete Dome facts

While investigating facts about Concrete Dome Homes and Concrete Dome House, I found out little known, but curios details like:

There is a concrete dome in the Marshall Islands containing tonnes of nuclear waste the US left there during Cold War testing and there is a large risk of it leaking due to rising sea levels. Nothing is being done about this.

how to calculate dome concrete volume?

The Roman Pantheon, built in 118 AD, is still the largest unreinforced concrete dome in the world.

What is domestic concrete?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is concrete dome. Here are 24 of the best facts about Concrete Dome Construction Techniques and Concrete Dome House Plans I managed to collect.

what is the purpose of the concrete domes?

1. Almost two thousand years after it was built, the Pantheon's dome is still the world's largest unreinforced concrete dome.

2. The US built a gigantic concrete dome to cover up one of its nuclear test craters

3. Halfway between the U.S. and Australia, there is a concrete sarcophagus called the Runit Dome. Essentially an American version of the Chernobyl sarcophagus, constructed to deal with lingering radioactivity within the Enewetak Atoll, site of 111,000 cubic yards of irradiated debris.

4. The Cactus Dome, a giant concrete dome on an island in the Pacific which was built to cover a radioactive crater.

5. At a US nuclear test site in middle of the Pacific, radioactive waste was buried and covered with a concrete dome. Cleanup was so poor that the dome fails American standards for landfills for household trash and radiation inside the dome is dwarfed by the radiation in the sediments outside it.

6. The Pantheon's dome is the world's largest non-reinforced concrete dome.

7. Around 4000 U.S soldiers where sent to Enewetak Atolla place located in the Marshall islands. The objective was to gather the residue of the nuclear bomb tests, and build a concrete dome to isolate the it. The the soldiers had no protection and were riddled with radiation related illnesses.

8. The Army Corp of Engineers tried cleaning up the Pacific test site by dumping all the contaminated soil into one of the detonation craters on Enewetak Atoll and capped it with a concrete dome. The dome is only 3m above sea level and is expected to be completely submerged within 30 years.

9. Runit Island has far worse a nuclear legacy than Bikini Atoll ever could and contains a concrete dome which houses 73,000 cubic meters of “hot” debris including exploded plutonium that is slowly leaching into the surrounding ocean which will near inevitably be swallowed up by rising seas.

Why are concrete blocks used?

You can easily fact check why holes in concrete blocks by examining the linked well-known sources.

There is an island in the Pacific Ocean that stores radioactive material from US nuclear tests. The only thing protecting it from entering the environment is a 1/2 meter thick concrete dome. - source

There is a concrete dome on Runit Island in the Pacific, only 46 cm thick, that hides a crater filled with about 73,000 cubic meters of nuclear waste. - source

There is a large concrete dome in the middle of the Pacific ocean. Locals call it 'The Tomb'.

When were concrete blocks invented?

Almost 2000 years after it was built, the Pantheon's dome is still the world's largest unreinforced concrete dome in the world. The height to the oculus and the diameter of the interior circle are the same, 142 ft.

How to build a concrete dome house?

The Pantheon was the largest dome of the world until 1881; is still largest unreinforced solid concrete dome

The Pantheon in Rome sports the largest unreinforced concrete dome in the world, even though it was built in 126 AD
