Re: Concrete quality

[Subject Prev][Subject Next][Thread Prev][Thread Next]
That is a British Standard for 25 MPa concrete (in a cube). That translates to about 3625 psi. Cubes reach higher strengths than cylinders, so if you are in the U.S. you can probably spec 3500 psi concrete and be OK. Conversely, you can spec 4000 psi to be on the safe side.

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?
