[papercreters] Re: Cement & Concrete FAQs (Frequently Asked Questions) Portland Cement Association (PCA)

Hi everyone ,i would try a hydrolic press it will have a pressure gage on it ,we did this and it started squising apart at 1200 psi.
A compressed block done in our press let go at 1630psi hope this helps.

What I'm wondering (and it's probably a very simpe thing) is how do you measure the psi? I can see putting a cylinder of cured papercrete into a jack or something and increasing pressure until it fails ..... but how do you measure how much pressure was applied?
