Hoover Dam Research Paper

When concrete is poured it contracts and heats up. This means that you cannot pour a whole lot all at one time or it will take years to dry if it is a big enough structure that you are building. A good example of this is the hoover dam which used over 3.3 million yards on concrete in the making of it. A common misconception is that they poured all the concrete at one time and waited for it to dry if they would of did it this way with all the heat that would have built up it would have taken over 125 years for it all to dry.

The hoover dam was built in just 5 years which was 2 years under schedule. The total cost of building it was $48.9 million. Concrete has been around for a long time and used to build big structures for thousands of years.
