DIVISION 10 CONCRETE MIXTURES

Everything You Need to Know About Concrete Strength | Cor-Tuf

Mar 31,  · While traditional concrete normally has a compressive strength ranging anywhere from 2,500 to 5,000 psi, UHPC can have a compressive strength of up to 10 times that of traditional concrete. After just 14 days of curing, UHPC has a compressive strength of 20,000 psi. This number increases to 30,000 psi when fully cured for 28 days.
