Broken earthenware spigot

C

In 1960s house. There is a wall hung toilet on the ground floor. The plastic drain stack is on the other side of the wall in duct. The tee is just above floor level going to the wc.

There was damp on the wall and further investigation showed it was the joint where the earthenware drain came in from the outside chamber and connected onto the plastic soil stack. Cement fills the gap between the plastic and the earthenware socket. The earthenware pipe is just above the concrete floor level.

A part of the earthenware socket was cracked and this is were the water was getting out. A piece of the socket has broken away leaving a hole. The piece can be placed back in to fill most of the hole.

How is the joint made up in this case?
Portland cement?

If Portland cement does it need mixing with sand?
Can small bags be bought from merchants?

There is some floor space around the joint to mound up any cement.
The toilet is out of use and the cloakroom toilet is being used.
Any input would be appreciated.

No chance of replacing the broken section with plastic ? This would give more peace of mind IMO :)

You can sometimes get small Mix-it-yourself cement+ sand bags @ diy stores :idea: You need a 1:1 mix . (I have a feeling you`re calling a socket, a spigot) ;)

Sorry, the socket in the earthenware pipe not the spigot - I have edited the post to suit. Are you saying that any normal 1:1 mix of sand & cement will do? It does not have to be Portland cement? Would it need PVA mixed in? Would a PVA mix be needed to wet the broken earthenware and surrounds?

The earthenware socket is only about 1/2" to 1" above the concrete house slab, the slab surface is not even at the bottom of this duct where the earthenware pipe comes in.

Is Jetcem any good? They make a whole range of this quick drying premixed cement. Is one any good for this purpose?

Portland cement is just a name given to cement when it was invented :idea: because it`s grey like Portland stone . NO PVA. 1:1 cement and building sand is the traditional way - Jetcem is also OK but may need a mix of sand ( may not , look on the bag ;) )

Thanks. What the bags say is what I posted above. Two items of Jetcem say it can do the same thing. Which one?

I intend to have the cement bond to the concrete base slab, to give a bigger area of cover.
