The tests indicated that the ultimate shear strength of it was a little larger than normal-weightconcrete beam's, and larger than lightweight concrete beam.
结果表明,高强次轻混凝土梁比轻集料混凝土梁的抗剪承载力有较大的提高,且比普通混凝土梁的抗剪强度大;

And reinforced high-strength lightweight concrete beam is less ductile as compared with the normal-weightconcrete beam of the same concrete strength.
