One of the modern finishing materials for building construction is igneous rock. This
study was focused on determining the relationships between mechanical and physical
properties of igneous rocks. This incorporates point load strength index Is (50) , Unconfined
Compression Strength (UCS), flexural strength, poisons ratio, dry density, porosity,
Schmidt rebound values and P-wave velocity for a wide range of igneous rocks. The
study was performed on data collected from the literature. The results showed that the
porosity has a significant negative effect on the dry density of rock samples. The best
relationship was observed between modulus of elasticity and temperature with the
coefficient of determination (R 2 ) of 0.89; it means that the temperature had a great
influence on the modulus of elasticity so that increasing temperature causes to decrease
in modulus of elasticity of igneous rock. In addition, the weakest relationship was
observed between flexural strength and p-wave velocity with R 2 of 0.42; whereas, there
was no relationship between UCS and Poisons ratio.
