Fire Retardant Are self extinguishing laminates, usually made with chlorinated resins and additives such as Antimony trioxide. These release CO2 when burning so when the flame source is removed, the self extinguish. Fire Resistant More difficult and made with the likes of Phenolic Resins. These are difficult to use, are cured with formaldehyde, and require a hi degree of post curing to achieve true fire resistance.

structural function, or both. Fire Resistance Rating (or fire rating), is defined as the duration of time that an assembly (roof, floor, beam, wall, or column) can endure a "standard fire" as defined in ASTM E 119 (3). Fire Endurance of Structures Figure 5 shows the effect of fire on the resistance of a simply supported reinforced concrete slab.

All of the manufactured sandwich composites resisted flame for more than 13 min and the fire resistance was positively affected by the density of the geopolymer layer. The development of composite materials from alternative raw materials, and the design of their properties for the intended purpose is an integral part of the rational management of raw materials and waste recycling.

Among the tests performed were physical properties tests, shape indices tests, mechanical properties and wear resistance tests, and weathering simulation tests. The investigations finally showed that it is a chemically and mineralogically pure, massive, strong, wear and weathering resistant, but, however, polishing susceptible, dolomite rock.
