Intumescent formulations incorporating melamine phosphate
Once familiar with the fire test rig constructed by M Kay, and modified to allow incorporation of both video and computer facilities, Melamine Phosphate production was scaled up from small to large laboratory scale, and then commercial scale production was considered. Samples produced at each stage …

Structural Assessment of Glued-Laminated Timber Columns Subjected to Real Fires
This thesis investigates the performance and post-fire structural integrity of glued-laminated (glulam) columns when exposed to real fires. The primary objective of the Mass Timber Demonstration Fire Test Program (MTDFTP) in Ottawa was to conduct large-scale fire tests to explore construction fire …
