The strength and hardness of concrete slab surface is considered significantly affected by bleeding of concrete. It has been reported that 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, as the sequence of the earlier experiment, two series of experiments have been carried out in order to examine the effect of mesh size of a filter mat and vacuum pressure ratio. As a result, the internal strength distribution of concrete slab gets to be more preferable as the mesh size becomes smaller and vacuum pressure ratio higher. Further, discussion has been conducted, based on the experimental results including the earlier ones, in order to find more reasonable and effective way in the application of the proposed vacuum processing method.
