-Conclusion & Discussion
Poisson's ratio is derived by dividing the horizontal strain modulus by perpendicular strain modulus. Poisson's ratio is a characteristic value of materials, and concretes have 0.16∼0.22 of it. The Poisson's ratio from the first experiment is 0.18 and this is comprised 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.
