혼합 비율에 따른 폴리머 콘크리트의 동적 물성 측정

초록

The purpose of this study was to measure the dynamic properties of the polymer concrete using longitudinal wave propagation method. Several kinds of polymer concrete specimens were made by different mixing ratio of aggregate and epoxy mortar. The frequency dependent variation of the polymer concrete stiffness and its loss factor was obtained using beam transfer function method. The effect of epoxy mortar ratio on polymer concrete loss factor was investigated because interfacial properties of mixed polymer composite changes vibration characteristic. Finally appropriate mixing ratio of aggregate and epoxy mortar compared to compressive strength, density, loss factor was identified to use noise reduction material in structure.
