Answer Posted / sagar sontakke
As soon as we add water to the dry content of the concrete, process of heat of hydration starts and this process will require a very long time to complete.Almost 90% to 95% of this process is completed within 28 days and remaining takes a year or two.This means that concrete attains 90% of the strength at 28 days. So to judge whether concrete has attained the desired strength, we have to test the concrete at 28 days.
