Internal Erosion initiated by water movement along channels called tunnel erosion, often
crack or defect the dam?s structure. It is one of the main causes of water structure?s (dams,
dikes, etc.) collapse. This phenomenon can be divided into 3 phases, tunnelling, collapse, and
the opening of the channel inside the dam [1]:
- ?Tunnelling? transport large quantities of particles due to the hydraulic gradient. It?s happen

- The ...

The use of the expansive cements to minimize the effects of the shrinkage is still little studied. Concrete, which is known for its durability, could not be implemented directly in concrete roadways construction. One of the biggest problems is shrinkage which occurs since it is in the paste concrete form. Shrinkage induced to cracking is not preferable in the roadways construction, which usually use the system of reinforced concrete and joint separating system. We will ...
