The Hoover Dam hasn&#x27;t even properly set yet!<p>Curing is an exponentially decreasing process, there will always be a little bit more concrete that still needs to cure, much like radioactivity half-life.<p>The Hoover Dam is quite an interesting piece of civil engineering, it broke ground in many ways other than the physical one.<p>Tons of interesting stuff here:<p><a href="http:&#x2F;&#x2F;www.usbr.gov&#x2F;lc&#x2F;hooverdam&#x2F;history&#x2F;essays&#x2F;concrete.html" rel="nofollow">http:&#x2F;&#x2F;www.usbr.gov&#x2F;lc&#x2F;hooverdam&#x2F;history&#x2F;essays&#x2F;concrete.htm...</a><p>Concrete, while on the surface very boring is actually a super interesting engineering material.<p>Another interesting tidbit: for the longest time the dam was actively cooled to whisk away the heat from the curing concrete (concrete curing is an exothermic process).
