Pre-tensioned bridge girder in precasting mattress, with single-strand tendons exiting in the formwork Pre-tensioning is a standard prefabrication strategy, exactly where the ensuing concrete component here is created off-web site from the ultimate structure site and transported to site at the time cured. It needs sturdy, steady end-anchorage details among which the tendons are stretched.
A tremie is usually a vertical, or in close proximity to-vertical, pipe using a hopper at the very best utilized to pour concrete underwater in a way that avoids washout of cement from the combine resulting from turbulent h2o connection with the concrete when it's flowing.
