Abstract
Nowadays lightweight concrete (LWC) is used on a large scale for structural purposes. The application of structural LWC in the construction industry has many advantages such as saving in dead load for structural design and foundation, reduce the risk of earthquake damage to structure, and good tensile strain capacity. Modulus of elasticity of concrete has been considered as a vital factor in designing concrete structures. However, in practice, the concrete modulus usually not measured, but estimated from the concrete compressive strength using empirical. Therefore, this study is conducted to determine the modulus elasticity of lightweight concrete by stress-strain in lateral and longitudinal direction. Hence, the poison ratio of LWC also determined. From this research, it was found that Poison ratio for the EPS-LWC enhanced with steel fiber is 0.17. Meanwhile, the modulus of elasticity is 13.79 GPa.
