Behaviour of Passive Fire Protection K-Geopolymer under Successive Severe Fire Incidents
The performance of a fire resistant coating for tunnel passive fire protection under successive severe thermal loading is presented. The material falls under the class of potassium based geopolymers (K-geopolymer) and was prepared by mixing ferronickel (FeNi) slag, doped with pure alumina, with a highly alkaline potassium hydroxide aqueous phase. Its performance was assessed by subjecting a con...
متن کاملFire-resistant Geopolymer Produced by Waste Serpentine Cutting
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...
متن کاملMicrocontroller Based Fire Protection System
Realization of microcontroller based real time fire protection system is considered and described in the paper. Given solution is based on application of microcontroller AT89S8253. The system is consisted of set of sensors connected to control device (microcontroller module). Control, monitoring and diagnostic are performed via computer of PC type serially connected with control device. Charact...
متن کاملComparison of the Effects of Different Fire Test Regimes on Passive Fire Protection Materials
In the past, HSE’s Health and Safety Laboratory (HSL) has studied the performance of a variety of passive fire protection (PFP) materials in protecting a part-filled LPG tank subjected to hydrocarbon pool fire engulfment. However, this is only one potential fire incident scenario that can threaten a process vessel; another is a jet fire, perhaps resulting from an ignited release from a leaking ...
متن کاملStudy of Metakaolin-Based Geopolymer with Addition of Polymer Admixtures
In the present work, metakaolin-based geopolymer including different polymer admixtures was studied. Different types of commercial polymer admixtures VINNAPAS® and polyethylene glycol of different relative molecular weight were used as polymer admixtures. The main objective of this work is to investigate the influence of different types of admixtures on the properties of metakaolin-based geopol...
