    Abstract
    Recently, there have been some building made from concrete structure fired. If a building is fired, the load capacity will decrease. Actually, concrete is a kind of fire-proof construction material. However, if a concrete is heated at more than 5000 C, significant strength degradation will occur (up to 50%). The strength degradation is occured due to decomposition process of C-S-H that are decomposited become CaO and SiO2,. It also can occur due to the difference of sublimation value between agregate and cement paste which can damage the interfacial zone, hence the coherent force among agregates will decrease. However, it does not mean that when a building is fired, this building can not be used anymore. This problem can be solved by using appropriate rehabilitation technology. There are some appropriate rehabilitation technology that can be used to rehabilitate a building after fire, such as : Coating method, Shotcrete method, Injection method (using epoxyresin), and Prepacked Concrete method for heavy damage. However, the level of the damage should be considered before choosing the rehabilitation technology method.
