note = {The paper describes the results obtained in an investigation of mechanical properties of lightweight aggregate concrete for structural use. Four typical domestic lightweight aggregate and a normal weight sand-and-gravel aggregate for comparison were selected, and the mechanical properties of the concrete produced with these aggregates and the relationships between these properties were investigated, to obtain the generalized structural design data. Comparing these kind of concrete, the values of static or dynamic modulus of elasticity of lightweight aggregate concrete are somewhat lower than the values of normal weight aggregate concrete of comparable compressive strength, but the Poisson's number, the relationships between various strengthes do not extremely differ from them of normal weight aggregate concrete. And the empirical formulas on the relations between compressive strength and static or dynamic modulus of elasticity, which are applicable to both lightweight and normal weight structural concretes, are derived. These formulas are useful to estimate the secant modulus or the compressive strength of concrete when they can not be determined by test.},
