Re: [Strawbale] Corrosion of iron by lime mortar

["andre leorat" <aleorat@gmail...>]

Thanks, i would like  to give  strength to the two lime  plasterd ( with GREB mortar)  wall covering the strawbale.
Polypropylene mesh is microfiber inside the mortar or wire mesh like, the ones used for fence during building construction or to take fish in the sea ?!

Thanks, andre

Galvanization only buys time. The zinc corrodes away instead of the
iron/steel. But after a time the zinc is gone and then the iron
corrodes.

Probably better not. The traditional answer would be hair but
polypropylene mesh is also used in the US. It may be better structurally
- it depends what you need.

Cheers, Dave
