One of the modern finishing materials for building construction is igneous rock. Thisstudy was focused on determining the relationships between mechanical and physicalproperties of igneous rocks. This incorporates point load strength index Is (50) , UnconfinedCompression Strength (UCS), flexural strength, poisons ratio, dry density, porosity,Schmidt rebound values and P-wave velocity for a wide range of igneous rocks. Thestudy was performed on data collected from the literature. The results showed that theporosity has a significant negative effect on the dry density of rock samples. The bestrelationship was observed between modulus of elasticity and temperature with thecoefficient of determination (R 2 ) of 0.89; it means that the temperature had a greatinfluence on the modulus of elasticity so that increasing temperature causes to decreasein modulus of elasticity of igneous rock. In addition, the weakest relationship wasobserved between flexural strength and p-wave velocity with R 2 of 0.42; whereas, therewas no relationship between UCS and Poisons ratio.
