    An Epi-DAM-ic? The Hoover Dam hasn’t been cured yet!

    One rather interesting piece of information that came to our attention this month is concerning curing.

    As many of you will know, curing is the process by which you can harden concrete by prolonging the reaction between the concrete surface and water. Concrete hardens by hydration anyway, but you can greatly increase its strength and durability by doing this over a longer period, usually between five and seven days and generally done up to a maximum of 28 days. During this time, the concrete is kept moist by constantly spraying it with sprinklers, covering it with wet burlap, or coating it with one of a range of commercially available curing compounds, which lock moisture in to the surface.

    The interesting fact is that the Hoover Dam over in good ‘ol USA still hasn’t finished curing yet, and has continued to gain strength at a slow and steady rate since it was built in the early to mid 1930’s. As you may imagine, the Hoover Dam is exposed to a significant amount of moisture every day, which continues to cure it. All concrete will continue to gain strength by curing if continually exposed to water, although this gain decreases exponentially as time goes on.
