So if the concrete of the questioned structure at the age of 28 days did not reach the specified required strength it means something went wrong the safety of post hardening which is the further hardening after 28 days is lost meaning that the value of the structure is less than could or should have been if the specified strength value The period of curing of concrete is most important as it is very essential for keeping the hydration process of cement with water until concrete attains the maximum compressive strength which increases but slowly after 28 days from initial placing time
