Key Points

This investigation aims to compare the mechanical properties of lightweight aggregate concrete with normal weight aggregate concrete.
Selected four types of domestic lightweight aggregates and one normal weight aggregate for comparison.
Conducted tests to measure static and dynamic modulus of elasticity and compressive strength.
Derived empirical formulas linking compressive strength to modulus of elasticity for both types of concrete.
Lightweight aggregate concrete shows lower static and dynamic modulus of elasticity than normal weight concrete of comparable compressive strength.
Poisson's ratio and strength relationships are similar between lightweight and normal weight aggregates.
Derived formulas can estimate the compressive strength and modulus of elasticity when tests are impractical.

The paper reports mechanical properties of lightweight concrete, suggesting design data for structural applications.
