There are more than half million tons of serpentine waste produced per year during mining operation in Taiwan. This study is to develop a process to manufacture fire-resistant geopolymer based on serpentine waste. The experiment results show that the waste serpentine-based geopolymer have very good physical/mechanical characteristics. For fire resistance tests, a 10 mm thick geopolymer panel wa...

Chaparral species of California, USA, exhibit three life history types in response to fire: non-sprouters (NS), facultative sprouters (FS), and obligate sprouters (OS). Adult non-sprouters are killed by fire; thus populations reestablish only through firestimulated seed germination and seedling recruitment. Facultative sprouters reestablish by both vegetative sprouting and seed germination. Obl...

The assessment of fire resistance for building constructions has been carried out by the solution heat engineering problem heating up structures under conditions non-stationary exposure with standard conditions. finite element method is used as method. Numerical simulation considered was using Ansys Mechanical computer complex, which allows a thermal design to be calculated on basis its softwar...

Background and Objectives: Earthquake can be the source of many secondary disasters. Fire is one of the most important secondary hazards after the earthquake. In some cases, post-earthquake fires, in urban areas, may cause far more severe damages than the earthquake itself. After the earthquake, the risk of fire is greatly increased due to the existence of sources of fire, such as arteries of g...
