| Research Abstract |
This research is about the pressure loss causing mechanism of high fluidity concrete with self compactability, when it passes through the obstacle. We use actual high fluidity concrete and model concrete with clear model mortal, and change the mix conditions of concrete and obstacle arrangement, we investigated the relationships between pressure loss and these parameters. Results of these investigations, in the case of that coarse aggregate blockage did not cause and the obstacle was single layer, pressure loss could be estimated with extremely precise, but in the case of dual layers of obstacle, the pressure loss cause mechanism was very complicated, then, estimated pressure loss value was estrangement from measured value.
