1950s Lightweight Concrete Compressive Strength
(OP)
I am currently using original construction drawings from 1959 to determine whether or not a roof stucture can support new imposed loading. The drawings show a " 2" lightweight pre-cast concrete plank" roof deck. This is the only information the drawings contain concerning the roof deck. What strengths were they making back then that I could used for an assumed value of f'c for the concrete?

2000 psi is a reasonable assumption without using special concrete testing equipment.
