Research on the Effect of Vibration Mixing Intensity on the Solidification Efficiency and Properties of Concrete

In order to further improve the efficiency of concrete in engineering application, the influence of vibration mixing intensity on the solidification efficiency and performance of concrete is studied. Four vibration intensity levels of 0g, 2g, 3g and 4g were selected to explore the initial and final solidification time and working performance of concrete under different vibration intensity. The test results show that when the vibration strength is 2g, 3g and 4g, the initial solidification time decreases by 4.9%, 7.5% and 8.7%, the final solidification time decreases by 1.5%, 1.9% and 2.7%, and the slump increases by 3.9%, 5.9% and 15.7%, respectively, compared with the vibration strength of 0g. Compared with 0g vibration strength, the compressive strength of concrete with 4g vibration strength is increased by 5.48%, 4.11% and 7.04% respectively at the age of 3D, 7d and 28d. The results show that with the increase of vibration intensity, the initial solidification time and final solidification time shorten, the slump increases, the compressive strength increases. Vibration mixing is of great significance to the application and expansion of concrete engineering.
