Abstract

The slump of concrete was tested by vibrating with a vibrating motor instead of manual rodding. The effects of different vibrating motor vibration forces, different vibration times, different concrete strength grades and different concrete slumps on the difference and deviation rate of the slump of concrete tested by the two methods were investigated. The research results show that it is better to choose an attached vibrating motor with a vibration force of 20kg and a vibration time of 6 seconds. When the standard slump of concrete is ≥140mm, the average difference between the slump of concrete tested by vibration motor vibration and that measured by manual rodding is less than 20mm, with a deviation rate of less than 15%, meeting the current requirements for concrete factory inspection in concrete production enterprises. It is feasible and practical to test the slump of concrete by using vibration instead of manual rodding.
