Mechanical Characteristics of Curing Concrete Affected by Forced Vibration

가력진동이 양생중인 콘크리트에 미치는 영향에 관한 연구

The purpose of this study was performed to estimate the mechanical characteristics of curing concrete affected by forced vibration. The major variables of this test were vibration method, vibration velocity and duration of vibration, The compressive strength, slip, bending strength and displacement are measured for all the cylinder paper molds and beams. The results can be summarized as follows ; 1)According to vibration, velocity(RMS), the compressive strength, bending and displacement for continual vibration increased, but for immediate vibration decreased. 2) Immediate vibration effected on concrete compressive strength, slip than continual vibration. especially in vibration velocity 3.59mm/sec(RMS; 0.624mm/sec) slip secreased 15% in continual vibration, 20% in immediate vibration.
