초록
In this paper, ultrasonic velocity(UV) test through OPC and Slag concrete is conducted considering porosity under compressive and tensile loading conditions. The test results show that up to 50% of compressive loading condition, UV a little increases and remarkably drops at peak load, however it fluctuates under the tensile loading condition because of the number of increase micro cracks in concrete specimens.
