Thread: Hydrated Lime?

Hydrated lime is used by builders as a component of mortar.

Lime used in mortar in old times was burnt in a fire to drive out the co2 which changed its properties so that when freshly slaked (mixed with water )it would form a good bonding agent in water.

Hot lime is extremely reactive and difficult to handle as it will boil cold water that it is added to. ( it's also allegedly good for disposing of bodies)

As an alternative hydrated lime was developed which is dried slaked hot lime. It works well as a building material when fresh but loses its ability to form good mortar as it absorbs water over time.

So in answer to your question it isn't dangerous but its probably not good for anything (in the building industry) either. Maybe useful for stabilising soil on roads or earthworks.

Hydrated lime is more reactive...

Not good to breathe it in! Or get on your skin...

And will burn veggies if not used very sparingly

You need to be careful handing it....hydrate isn't as reactive as quick lime but can still burn. You should see the PPE we have to wear when handling it.

Main risk is Lime in Eye, it reacts with water and your eyes have plenty of moisture. Where glades if you are busting a bag open, you only have one set of eyes.

Out of interest who manufactured the lime??

You could give it to a farmer, they will fine a use for it.

It is labeled Cement Australia.

I just want to get rid of it, I can not think of any use we would have for it & have no idea why it was ever bought (that's like a few things I have discovered here).

I Googled the stuff & they say it may be used in water/sewerage treatment for something? We have a very strange septic/sewerage set up with 4 separate septic tanks that all run to 1 larger septic tank which is then pumped into the towns sewerage system. I have found records that the pump for this has failed & the whole yard has been covered in sewerage.
Maybe it was used to help clean that up?

Anyway, I have decided to offer it to the council, as long as they come & get it, for free. Maybe they can find a use for it.

Thanks for the information & advise.
