Measuring Dynamic Young’s Modulus of Low-Density Foam Concrete Using Resonant Frequency Test

Foam concrete is a cellular material mainly used in construction. Because of the low-strength feature foam concrete, conventional testing methods such as strength measurement are insufficient to characterize key attributes especially for low-density that commonly designed functional purposes. Inspired by nondestructive resonant frequency test, this study investigates feasibility using method evaluate dynamic Young’s modulus at range. Three variables typically alter mechanical properties considered evaluating robustness approach—bulk density, water-to-cementitious ratio, and fly ash replacement ratio. The fundamental transverse found be most suitable determining modulus. experimental results demonstrate good accuracy approach measuring different samples. It also confirmed can accurately if bulk density solid its base cement paste known.
