Get a core sample of the floor tested, have come across two floors here where the screed was at fault a bit like tiling on bonding, lime is a pain in the ***

Tested for what??

Tested for what??
Sand/ binding agents or just to rule out the screed

Nope still not with. What tests are you suggesting??and how will those test results "rule out the screed"?

So your saying the screed cannot be at fault and not to question it at all.

No I'm not saying that at all. What I'm asking is what test are you going to request that a core sample will satisfy and what answers are you seeking in doing such tests. Test for binder/sand. This is petrology and will tell you if sand and binder are present. If the screed is hard there is binder and most likely sand present....

No I mean for sand quailty

Anhydrite screeds are made in ready mix facilities where they are subjected to quality assurance regimes. The sand used is specially selected and tested for suitability by the binder manufacturers (us). The measure of sand quality is usually determined by how quickly the screed hardens. Ergo you will prove that the sand is of good quality and suitable for inclusion in the screed by doing such a test. We already know the answer before the screed is made. Same with the binder. It is unusual in the extreme for there to be anything aims with the individual components of the screed such that standard statistical process control will take care of things. Add the sand and binder together with water and you have a screed mortar. There really isn't much to go wrong during the manufacturing process itself.
