High Strength Concrete in the Precast Concrete Industry

survey revealed that the average 28-day strength of concrete in the industry is 6000 psi (41 MPa). The maximum strength that producers feel they can reliably supply is 8500 psi (59 MPa). There appears to be little reliance on admixtures other than superplasticizers.
