underwater concrete casting
underwater concrete casting
(OP)
we are doing a project, where most of the concrete casting is below the sea level (including the formwork). we intend to use sikament antiwashout admixture with the concrete mix. Is there anything we should pay particular attention to when pouring the concrete (using pump)?





RE: underwater concrete casting
With the tremie system: When concrete flow has been established, maintain the flow and keep the end of the tremie pipe below the surface of the concete. This forces fresh concrete (from the pipe) to the bottom and insures that it does not come in direct contact with water.
With a pump you are doing the same thing, just using the pump's pressure instead of gravity. The same logic should apply.
Best Wishes
