I am doing estimating for projects in rural foreign countries where, read-mixed concrete is not available, and they have to either hand mix or use portal concrete mixer.
Can anyone tell me how to mix cement, sand, gravel, water, etc. by weight, to make 3,000 psi, 22.5 MPa?
Thank you for your...

If ACI doesn't has any super-p requirements, do you kow any rule of thumb from concrete engineering points of view?
So far all I found out is to use super-p on 10,000psi or higher strength, on shearwall and/or...
I am a structural estimator and have priced many higrise concrete structures from 20 stories up to 50+ stories and just run into a debate of Super-P use.
After spent time digging out these old project data, I found out that every project is different in specifying super-p, even the same...
