Abstract
In this study examined the application of borehole point load test the deterioration diagnosis of the alkali silica reaction of a concrete degradation phenomenon. The borehole point load test was an examination that examined in a concrete core hole. And, the compressive strength and modulus of elasticity of a concrete structure coefficient were tried by this examination. In the result, compressive strength and modulus of elasticity in the core gathered from a concrete test piece and a deteriorated structure were the same as the estimation of borehole point load test. In addition, the decrease in the modulus of elasticity coefficient because of the alkali silica reaction was able to be confirmed by the borehole point load test. It has been understood to be able to use the borehole point load test to diagnose concrete above.a
