Characteristic of Mortar-Containing Waste Tyre Powders and Flame Retardant

The purpose of this study is to determine how effectively waste tyre recycled material mixed with non-fire agents work in combating fire. As discovered in the previous study, waste tyre mixed with cement mortar has more insulation capacity. However, this mortar is weak against fire. Therefore fire retardancy agents, with a specific proportional mix, will be added to increase its fire prevention capacity. Tests will be made in accordance with ISO 5657 procedures for measuring fire ignition time, flame and shape variation of test pieces at the Building Material Test Institute. The test piece will be set up with horizontal levels having a constant radiation heat of l-5W/cm. Temperature transfers and increases from the surface into the interior. Combustible gases result due to pyrolysis, and regular contact is maintained between the fire source and the center of the test piece for assessment purposes. Ignition has not been occurred without adding retardant meaning that there is almost no possibility of ignition of waste tyre particle. This fact can be considered into fire load to appreciate a volume of combustion materials. Flame is not occurred due to beat-absorbing effect by adding non-organic series retardant into waste tyre particle. Conclusions have been summarized as follows; (1) Combustion of building material can be decreased by adding retardant to waste tyre-mixing mortar. But compressive strength and insulation capacity of the material should be measured later. (2) Firing prevention and ignition are main points of building fire. Reasonable fire engineering assessment of interior material should be made for establishing effective disaster prevention system.
