#38 Concrete Pour Runs into the Night

Description:  When pouring concrete contractors cannot simply begin or end placing concrete at any given location in a structure during a given pour.  Due to many reasons, including rebar placements and concrete’s inability to stick to itself once dry, pours need to be done in a manner that completes a predetermined structural element.  In some cases, this means pouring thousands of yards of concrete in one continuous operation for hours and even days.  Pictured above is a concrete pumper’s boom working into the night on a  2,000 yard pour.  The pour was comprised of approximately 200 trucks full of concrete and that lasted more than 12 hours.  In the background of the photograph is the job’s tower crane silhouetted against the setting sun.
