Lime plaster conduit protection

[tvrulesme]

I've read many threads (some true, some not) about cement corroding copper, MDPE, cables sleeving etc.

 

Could anyone tell me if lime plaster reacts with anything or if it's safe to bury things directly? Trying to work out what can be put in the walls unprotected and what will need conduit etc. 

 

Any experts, same question with limecrete (NHL 5) please.

There are metal conduits that have been covered with sand lime for decades 

As with a previous thread wet plaster especially lime doesn’t stick to plastic 

So metal (ally) capping will be fine
