1 and 2 was in range of theoritical value. This shows there was proper uniformity in between well attached strain gauge and cylinder.
- Shear strength compressive strength of cylinder 1 and compressive strength of cylinder 2 measured by using shear strength of cylinder.
- Dry shrinkage showed 13.56% of error by limitation of measuring tools, however, we could find out shrinkage of concrete.

in the range of theory, and the value from the second experiment is 0.16 which also comes under the range of theory. In case of specimen no.1, there was an error of 12.6% but the Poisson's ratio is highly appropriate. From this, we can analogize the Poisson's ratio has nothing to do with strength, but is related to the materials.
