Abstract
This paper presents vibrating properties of ferrite-cement composite materials which are produced through mixing ferrite byproducts coated with asphalt and cement. Logarithmic decrement, δ, and modulus, Ef0 were calculated from decay curves for damped mechanical oscillation and resonance frequencies, f0, for the fundamental bending vibration for a specimen hung at the modal points.
It was found that coated ferrite concrete had high density, high mechanical damping constant and high rigidity. Moreover, the more the coating asphalt, the larger was the δ, the lower was the f0 and the lower was the Ef0. The effect of asphalt's penetrations on the vibrating properties of ferrite concrete was a little.
