Why were the builders able to build the Hoover Dam and get the concrete to dry?

Concrete does dry as it solidifies, but the water used in the mix does not evaporate and leave the remaining components of the concrete in place as a solid. When concrete sets the water chemically reacts with the solids and is incorporated into the now solid material.
The main problem with the setting of the concrete in Hoover Dam was to remove the heat generate in the setting process. The concrete was poured in such thick blocks that the internal temperature would have risen to damaging levels without special procedures to remove this heat. Coolant was circulated through pipes laid in the concrete to remove this heat.
