Experimental Study on the Development of Vibration Controlled Concrete

진동제어 콘크리트 개발에 관한 실험적 연구

Construction activities and operation of transportation facilities have caused unfavorable effects such as civil petitions associated with vibration-induced damages or nuisances. The objedtive of this research is to develop vibration-controlled concrete containing foams, latex, rubber powders, plastic resins and etc as a concrete mixture. As the first step to achieve this research, preliminary mix designs have been carried out to find out an appropriate mix proportion above 200kg/㎠ in uniaxial compressive strength, and investigate their dynamic mechanical characteristics such as dynamic elastic moduli, material damping ratio, Poisson's ratio, resonant frequency and etc.
