Advantages

- Direct measurement of the compressive stress present within the masonry.

- Useful for determining stress gradients within a masonry wall or column.

- Can be used to determine the in-situ stress and compressive strength of masonry structures.

- Provides information on the existing state of stress as well as the stiffness and strength of masonry.

Limitations

- Requires the cutting of a slot in the masonry, which may cause damage to the structure.

- Can be time-consuming and labor-intensive.

- Requires specialized equipment and trained personnel to perform the test.

Suitable for:

- Evaluation of existing masonry structures such as walls and columns.

- Determining the in-situ stress and compressive strength of masonry structures.

- Structural evaluation of existing structures.
