Why We Test Concrete Compressive Strength after 28 …
After 14 days of casting concrete, concrete gains only 9% in next 14 days. So, rate of gain of strength decreases. We have no clear idea upto when the concrete gains the strength, 1 year or 2 year, but it is assumed that concrete may gain its final strength after 1 year.So, since the concrete strength is 99% at 28 days, it's almost close to its final strength, thus we rely upon the results …
