3000 psi vs 4000 psi concrete - Structural engineering

I have found over in Asia on project specific batch plants that one might have a 3000 psi mix design but when the concrete is tested at 28 days, it'll be 4000 or more from time to time and usually always more than 3500. Hundreds of tests on several projects have confirmed this. We have had some 20 MPa concrete test out at nearly 40 MPa.
