Abstract
In this study, various laboratory tests were conducted to evaluate the effect of the moisture conditions of Jeju basalt on the mechanical properties. Twenty specimens were produced respectively from basalts collected from Sangga-ri and Eoeum-ri in northwestern Jeju. The tests were performed under saturated and dry conditions, and the results of these tests were used to examine the relationship with the physical properties and the mechanical properties depending on the moisture conditions. As a result of analysis with the test results and references, it was found that the uniaxial compressive strength, Brazilian tensile strength and elastic modulus in the saturated condition decrease at a similar ratio as compared with the dry condition. Also, the Brazilian tensile strength and the uniaxial compressive strength were in a linear proportional relationship, and in the moisture conditions, this relationship was not significantly affected.
