With this review, experimental samples of gypsum wallboard ended up exposed to numerous warmth fluxes at various durations using the ASTM E1354, Cone Calorimeter radiant heater. Schroeder was capable As an example that a crystalline transform would arise inside the gypsum wallboard when heated by using an x-ray diffraction system. His results show that gypsum wallboard was the only real content that can be reliably used for predicting depth and duration applications. On the other hand, Schroeder’s examine did not develop a successful suggests for employing this technique into a scene inspection.
