So we can’t predict the strength until the concrete comes to that stable state. Once it attains certain strength at 7 days, then we know (according to the table) only 9% of strength going to increase. So at sites, we do normally test concrete at this interval. If the concrete fails at 14 days, then we will reject that batching.CIP 35 - Testing Compressive Strength of Concrete,2003 HOW to Test the Strength of Concrete? • Cylindrical specimens for acceptance testing should be 6 x 12 inch (150 x 300 mm) size or 4 x 8 inch (100 x,Compressive Strength of Concrete & Concrete,Understand what is compressive strength of concrete & how compressive strength is determined from test specimens for practical design of concrete members,
