Among the index properties of granite and andesite, the relation between porosity and water content is highly correlated, but specific gravity, porosity and water content have loW relation with P wave velocity and their relationship showed dispersed zone type. With raising the temperature, Brazilian tensile strength was not changed remarkably, but decreased near $100^{\circ}C$. After the strength increased at $150^{\circ}C$, it decreased near $200^{\circ}C$ in granite. In andesite, however, the strength was increased up to $200^{\circ}C$, and then decreased. The variations of P wave velocity at each temperature zone are similar to those of tensile strength.
