Influences of Environment Vibration on the New Constructed Concrete Strength

Abstract

Based on the field measurement and combined with relevant references, the different sinusoidal vibration parameters are selected and applied to new constructed concrete by vertical vibrating table. The concrete compressive strength for different ages is discussed, and the influences of some factors including different vibration time (before initial curdle, between initial curdle and finial curdle, after finial curdle), different vibration energy. From the experiment results, the following conclusions can be concluded, the new constructed concrete compressive strength is increased when the vibration energy is lower, and decreased when the vibration energy is higher, and the new constructed concrete strength affected by environment vibration obviously before initial curdle time.
