anhydrite screed

Hi guys

anhydrite screeds - I'm pricing a job up and im not 100% sure if it's a anhydrite screed. Is there a way of finding out quickly?

Thanks

 

I asked Alan Jackson the same question, his answer is in the second question of the post below.

In short, they tend to be thinner, self compacting and mostly I don't think they add chippings. Which I think is one of the easy ways to distinguish them from standard concrete slabs. Chalky as well..

 

If you can see a cross section you will know, another way to tell is besides the latiance is its a lot whiter than screed and will have no stress cracks in floor.

If you take a stone to a section it will rub down like levelling screed.

 

Ask the customer or builder.

 

throw some screed on and see if it pops?.. I know that was no use to anybody...lol
creamy white in colour and if you give it a quick rub with a stone you'll see the skin come off..

 

Mario, you so need to get on that Ukflooring installers Facebook page...You'd have a ball!!

 

Don't know if I could take the strain of it all...

 

Pull ya pants up and come on over ya big girls blouse

 

Found this in regards to more info on anhydrite or seemingly dihydrite, and any news Matt on your idea on testing?
