Re: Concrete quality

This is likely a British Standard for 25 MPa concrete which would be 3626 psi.  Probably best to specify 4000 psi.

Subject:        Concrete quality

I have a break press machine coming in from overseas, we are to design the foundation for it.  The drawings for the press recommend a concrete quality of “BS 25”.
Does anyone have knowledge of what the  BS 25 means?  A US equivalent?
