Concrete mix suitable for immersion in seawater - any suggestions? |
|---|
| message from Iain Donaldson on 18 May 2004 |
I live on the Scottish Coast in a small settlement that has no mains
drainage. We void our house sewage directly to the sea via a 6" cast
iron outfall pipe with an outlet to the mid-tide line - don't ask it's
Scottish Water's problem to comply with EU Directives by next year!
The outfall is supported at intervals on concrete piers of about
1000x800x600 DWH. The shore is pebble and rock. We are exposed to
Southerly storms. Two of these piers are crumbling away in a pretty bad
state and need to be recast. I guess that I will just trim down the
existing piers, build some rectangular formwork and pour concrete...
more or less.
My question: any advice about type of cement? should it be rapid-set?,
what mix? and are there any special additives that might help to keep
strength and minimise corrosion in the pipe when the piers are immersed
in seawater 50% of the time.
It may be that someone has experience of casting concrete as a seabed
mooring with chain if no direct experience of sewer pipes.
Cheers

It might be a good idea to upgrade these supports while you have the chance so you
might be able to glean some more information from these people:
