![]() The pipes that were used to cool the large blocks were later filled with concrete for additional strength. Crews relied on 1,000-pound blocks of ice produced daily at the site’s ammonia-refrigeration plant. Nearly 600 miles of steel pipes woven through the concrete blocks significantly reduced the chemical heat from the setting for the concrete. Crews, however, used some innovative engineering methods to hasten the process. The Hoover Dam concrete would cure in 125 years by conventional or natural methods. Columns of blocks were linked in alternating and interconnecting arrangements. Widths of the blocks varied from 25 square feet to 60 square feet depending on the blocks’ location. The Hoover Dam’s base required 230 blocks of concrete, each block five feet in height. During peak production, concrete buckets were delivered every 78 seconds. Railcars carried the fresh concrete for the dam in 4 by 8 cubic-yard buckets with overhead cableways lowering the concrete to the dam forms. Two concrete plants were built on the project site for construction. Government officials decided to rename the dam in honor of Hoover however, the name change became official in 1947. Secretary of Commerce Herbert Hoover’s negotiations over the 1922 Colorado River Compact to direct the water to the seven nearby states was met with legal challenges until President Calvin Coolidge authorized the project in late 1928. Construction of the dam would eventually cost $49 million ($700 million by today’s valuations). In 1922 bureau director Arthur Powell presented a plan to Congress for the dam in Black Canyon. The 7-year timeline for dam construction, however, proved initially challenging, although contractors were later able to complete the project in four years, by 1936. Originally named The Boulder Dam, its purpose was to corral the Colorado River, to harness the river’s power to provide electricity for the growing Southwest, and to direct water to developing agricultural regions. Bureau of Reclamation developed plans to build the dam along the border of Arizona and Nevada nearly a century ago. Simply put, it’s the way the dam was built, a modern marvel even by today’s standards. What makes this man-made structure of 3.3 million cubic yards of Hoover Dam concrete so magnificent and so seemingly everlasting? And only an architect would say it’s probably the Hoover Dam, the massive concrete structure built on the Colorado River in the early 1930s. Only an anthropological engineer would imagine what monuments of human civilization would survive the longest for other intelligent life to examine. It is not just the water throw anything down there and it will flow upwards but make sure that nothing strikes your head because the push from the air is too damn strong.Only an anthropologist would imagine a world without humans. The flow of air upwards trough the edges pushes everything upwards, hence nullifying even overcoming the gravity. The answer is that the construction of this dam is such that the flow of air becomes way too strong. The scientists have a rather satisfactory answer to this mystery. You will be amazed by the sight that the water instead of going down, will move upwards. Bring a bottle with yourself, stand on top of the constructed area, open the bottle and try to pour the water down. If you visit this place, do some self experimentation. ![]() The size of this dam is gigantic, but the size does not matter because the sight that you might see is too spinning for you to consider the size. The Hoover dam is one of the main tourist attractions in the eastern US. Instead of trickling down its concrete wall it will reverse course and shoot up into the air. All you have to do is open up a bottle of water, reach out over the edge of the dam, and start pouring it out. ![]() And there’s a cool little experiment you can do that will prove it. At the Hoover Dam, you can actually pour water straight up into the sky.
