Outline of Final Research Achievements

This is an experimental study for improving the fresh properties of concrete using the Variable Mixing Speed Concrete Mixer developed in the study. In the experiments the effects of mixing method and mix proportion on the fresh properties and strength of concrete was investigated.
As the result, it was found that power consumption for mixing influences on the properties of concrete, and the fresh property can be evaluated during mixing by observing the electric power.
