Improvement of behavior against fire of plastic waste added in plaster panels

In the field of construction materials, the requirement of Fire Resistance tries to reduce the chances of an uncontrolled fire starting or spreading. This not only affects the danger involved in the destruction of the element of which the construction material is part, but also the risk that arises from the production of flue gases during the fire.This study proves that the incombustibility of the plaster contributes to the improvement of the behavior of the plastic waste in a fire, providing it, for a time, a physical mechanism of protection. During a fire, the concentration of CO2 generated by gypsum panels with plastic waste added, assuming complete combustion, would not exceed the amount considered as a risk to people's health. The calculated CO values were very high but other factors such as the total amount of synthetic materials inside the rooms must be taken into account. These synthetic materials would emit CO before the panels with plastic waste, whose emissions would be delayed by the physical barrier of the plaster.
