Does higher psi concrete crack less?
Increasing the cement content raises the psi, resulting in greater resistance to bending due to load factors and less cracking. The type of fiber used to thicken the slab has no effect on its strength. Thickened slabs are about 10 percent stronger than standard slabs of the same thickness.

When was 2500 psi used in concrete?
I can recall in the early 1950's when 2000 or 2500 psi concrete was used in suspended slabs and beams. Durability was not considered much in those days and the saving was deemed substantial (at least by some of the contractors with whom I dealt). The general trend since that time has been toward higher strengths and of course, there are now many additives which were not available in the fifties.
How much pressure should I use for concrete?
The strength of concrete that you use is regional, industry, and schedule driven. We specify 4,000 psi and receive almost 6,000 psi because contractors want to improve on schedule. My brother, in another region, has worked jobs where 7 day strength was 1,000 psi, and isn't worried because, with the admixtures, it will be 3,000 psi eventually. You should use a strength that is normal for your region because it is economical.
What is the coefficient of variation of concrete modulus?
The coefficient of variation of concrete modulus is very high . The modulus of concrete can vary +/- 20%. Couple that variation with the likelihood that actual strengths will be 1200 psi or more than the specified, and you are left arguing within the margin of error.
What is the difference between high strength and normal concrete?
About the only major difference is the "normal" concrete at least gives some warning before failure while the high strength concrete fails almost instantly. Wouldn't consider either to be what I would call "ductile" though. Spec the concrete strengths you need or can achieve without much cost or hassle.
