- Abstract
- Recent construction activities have given rise to civil petitions associated with vibration-induced damages or nuisances. To mitigate unfavorable effects of construction activities, the measures to reduce or isolate from vibration need to be adopted. In this paper, a vibration-mitigated concrete(VMC), which can be one of pertinent measures for reducing vibration, was investigated to be used as a vibration-mitigated concrete wall and pavement. The concretes were mixed with various vibration-reducing materials, such as latex, rubber powder, plastic resin or polystyrofoam. Normal-and high-strength concrete specimens were also tested for the comparison. A total of 14 cylinders and 14 prisms were tested to investigate their dynamic material properties by the forced resonance test. Wave measurements on concrete specimens showed that vibration-mitigated concrete has larger material damping ratio than normal-or high-strength concrete. Polystyrofoam turned out to be the most effective vibration-reducing mixture.
