ACI Concrete Strength Testing Technician Practice Test

Is ASTM C1231 applicable instead of ASTM C617 for capping requirements?

1. Yes, it can be used instead

2. No, both must be followed

3. Yes, but only for specific materials

4. No, unless special permission is granted

The correct answer is: Yes, it can be used instead

ASTM C1231 provides an alternative method for capping concrete test specimens, specifically for when the typical capping materials specified in ASTM C617 are not available or practical to use. Capping is an important step in preparing concrete specimens for strength testing, as it helps ensure a proper load distribution at the ends of the specimen during testing. Using ASTM C1231 allows for flexibility in the materials that can be used for capping, provided that the alternative materials produce results that are comparable to those obtained with the conventional capping methods. This can be particularly useful in field testing or in situations where traditional capping materials may not be readily available. It's essential to note that while ASTM C1231 allows for alternative practices, it does not negate the need for compliance with ASTM C617 when required. Therefore, in scenarios where ASTM C617 is specified, it is important to follow those guidelines unless a clear exception is made in testing protocols or standards. This understanding underscores the importance of having the flexibility to adapt testing procedures while maintaining the integrity of strength test results.
