Measuring Compressive Strength - Precast concrete

A concrete compressive strength test machine works by progressively applying force on a specimen. Because strength is defined as the maximum load carried divided by the average cross-section area, the most logical way to determine the strength of a specimen is to load it until it fails.

Standards for 7-day and 28-day strength test results

According to section 19.2.1.3 of ACI 318-14 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents. 3- or 7-day test results are used to monitor early strength gain, especially when high early-strength concrete is used.
