concrete cube crushing test qatar

Another disadvantage is a slower rate of gain in strength. Cube crushing may not result in concrete gaining designed 28-day strength for high fly ash mixes and may fall short of it. This is where the designers and specification writers should make some hard decisions. Specify the acceptance criteria to …

Concrete Cubes Strength If 28 days result less than 7 Days

Sep 20, 2013 If the cubes have a failed test result at 28 days, then the spares will be used to test for either 42 days or 56 days, depending on what test age you prefer beyond 28 days. Two cubes will be tested again with the same cube ID number, but these will be spares. But I think the case you mentioned rarely happened, so you can follow the above action ...
