| Research Abstract |
It is well known that salt rock layer is widely deposited under the Eurasian basement. Underground water contains weakly salt where the salt rock layer is occasionally deposited near the ground surface. Such a typical example can be seen in the northeast area of Thailand. Agricultural productivity decreases due to the salt damage of that the salty ground water level gradually rises resulting in appearance of salt crystals on the ground surface associated with annual repeat of rainy and dry seasons. This research project is intended to develop a numerical computation technique to reveal the mechanism of salt damage which will lead desertification. On the other hand, paper sludge discharged from paper manufacture causes a serious environmental problem. Such sludge can be changed to porous stable ceramic materials by burning it at 1300 degrees. This research project also aims at utilizing such materials to protect and repair the salt damage.
