If the cube has a failed test result at 28 days, then your spares will be used to test on either 42 days or 56 days, depending on what test age you prefer beyond 28 days. Two cubes will be tested (or crush concrete cubes) again with the same cube ID number, but these will be spares. So most probably, a test beyond the 28-day test is likely to

The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days after casting).

From the above table, we see that concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days and 99% strength in 28 days.thus, it is clear that concrete gains its strength rapidly in the initial days after casting, i.e.90% in only 14 days.

For cube test, 65% of strength achieved with in the 7 days of casting date makes so early to gain the strength but later 99% strength takes more than 2 weeks approximately 21 days later achieving strength takes lot of time after 7 days and it gains 99 for 28 days, so only we check for 7 days n 28 days for cube test results.
