Why We Test Concrete Compressive Strength after 28 Days?

Aug 14, 2014The table below shows the compressive strength gained by concrete after 1, 3, 7, 14 and 28 days with respect to the grade of concrete we use. From above table, we see that, concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days and 99% strength in 28 days.

Why We Test Concrete Compressive Strength after 28 Days?

When, its strength have reached 99% in 28 days, still concrete continues to gain strength after that period, but that rate of gain in compressive strength is very less compared to that in 28 days. After 14 days of casting concrete, concrete gains only 9% in next 14 days. So, rate of gain of strength decreases.

Testing the Compressive Strength of Concrete — What, why

The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units.
