1561 Concrete Compressive Strength Limits

Table 15.11 gives the maximum concrete compressive strength limits for high-strength concrete, and with the shapes and sizes of the corresponding standard compressive test specimens used in different countries [71-75]. Although ACI 318-02 has no upper limit on the compressive strength itself, there are limits on the compressive strength that can be used in some design equations (e.g., development length and shear). CSA A23.3-94 and NZS 3101-95 have reduced limits for the concrete compressive strength
