mum compressive strength of 500 psi [ MPa], which is about two days after placement for most concrete maintained at 50°F [10°C]. Low concrete temperature has a major effect on the rate of cement hydration, which results in slower setting and rate of strength gain. A good rule of thumb is that a drop

The development of the strength starts after 7 days the common strength values is 10 MPa (1450 psi) to 40 MPa (5800 psi). At about 28 days 75 80% of the total strength is attained. Almost at 90 days 95% of the strength is achieved. See Also: Concrete Tests | Properties of Concrete . Air Entrained Admixures ; Properties of Fresh Concrete

There are many factors contributing to the reduction of strength after 28 days. It's depend on the performance of the concrete itself and subjected to intrinsic properties and also the environment of the concrete to be exposed as well. However, design is normally based on the strength of the concrete the age of 28 days.
