We had a concrete slab that had some static flooring installed. The install passed as a conductive floor but failed as a dissipative floor. The mix contains type 1L cement and it was discussed that the increased amount of limestone could cause the concrete to be more conductive and may have an impact on the performance of the static flooring.
Has anyone ever experienced this and what was your solution to have a low carbon concrete, or at least one with type 1L and preventing the conductivity of the concrete from impacting the finish surface?
Good evening, Jaclyn. I work with cement and cement producers very extensively but I’ll have to confess that I’m only somwehat familiar with the concept of a conductive floor vs dissipative floor. If I understand correctly, the floor is too insulative? I suppose that’s possible but I don’t think the limestone fraction of the PLC/IL alone would be the cause. PLC based concretes tend to pass less charge in a chloride permeability test. While that test isn’t necessarily related to your concern here, it may be related.
What I’d like to do is to get you in contact with some industry experts that should be able to help with this. I’m at nathan.forrest@cncement.org - if you want to send me an email with a little more info, I think I can connet you with the right folks.
