Standards for 7day and 28day strength test results
According to section of ACI 31819 the specified compressive strength shall be based on the 28day test results unless otherwise specified in the construction documents. 3 or 7day test results are used to monitor early strength gain, especially when high earlystrength concrete is used. However, 3 and 7day test results are not commonly used for acceptance purposes.
