This study investigates relationships between the modulus of elasticity with compressive strength, splitting tensile strength with compressive strength and modulus of rupture with a compressive strength of the pumice and scoria lightweight concrete. The modulus of elasticity is expressed in term of the square root of the compressive strength and combined power function of density with the square root of the compressive strength. While the splitting tensile strength and modulus of rupture are expressed in term of square root and in power function of the compressive strength. The results showed that the modulus of elasticity is precisely expressed in term of combined power functions of equilibrium density and the square root of compressive strength. While the splitting tensile strength and modulus of rupture are precisely expressed in term of the power function of compressive strength. All empirical formulas are expressed by the empirical coefficients that are not significantly different between both lightweight and validated by codes then it may be applicable to them together. © School of Engineering, Taylor’s University.
