Question: 1 / 400

What must be aligned during the testing process of the specimen?

Surface area with the load

Axis of the specimen with the center of thrust

During the testing process of a concrete specimen, it is essential to align the axis of the specimen with the center of thrust of the testing machine. This alignment is crucial because it ensures that the load is applied uniformly along the central axis of the specimen, which helps to prevent eccentric loading and ensures the accuracy of the test results. Eccentric loading can lead to inaccurate measurements of compressive strength or other failure metrics, which might misrepresent the specimen's characteristics. Proper alignment is a fundamental procedure to guarantee the integrity of the test and the reliability of the data collected.

The focus on alignment with the center of thrust emphasizes that the load needs to be evenly distributed to avoid any shear forces or moments that could affect the specimen's performance during the test. Thus, maintaining correct alignment is vital for achieving valid testing outcomes.
