Which Cement is the best to build a building.Like 5000 PSI or 8500 PSI, what is the different in between them, or they use for.Thanks
Yes the PSI rating of cement is it's strength rating. But the higher rated cement is more expensive, and it is heavier. So maybe you would use the higher rated cement for the foundation and the lighter stuff for the higher floors. The design of the building would take all this into consideration to provide a structure that meets code but does not cost too much.

First of all, cement is not concrete and you are referring to concrete which is a mixture of cement, water, and a mix of aggregates. The higher strength concrete of 8500 psi is best used for concrete columns where high axial loads are present. 5000 psi can be used for elevated beams and elevated slabs. Foundations are typically 3000-4000 psi only. With higher strengths mixes, the water-cement ratio is critical. In my job as a structural engineer, I mostly deal with 3000-4500 psi. The strength of the concrete mix is completely independent of the unit weight of concrete. Concrete is assumed to weight 150 lbs/cubic foot regardless of its strength.
