The strength and hardness of concrete slab surface is considered significantly affected by bleeding of concrete. It has been reported that dewatering by vacuum processing is quite effective to obtain high density of concrete. The method, however, has not been successfully used for the concrete work in the field of building construction, compared with that of civil engineering works in Japan. In the present study, firstly the state of the art concerning vacuum processing method is reviewed and the newly proposed vacuum processing method is introduced. Then the effect of the proposed method on concrete properties of slab is examined by a series of experiment in order to find more reasonable and effective way in the application of the proposed method.
