Fire Exposure Response of Alkali-Activated Concrete Modular Prototype Panels
The fire exposure of conventional concrete has been extensively explored to understand the damage scenario in the concrete subjected to direct fire events. However, the conventional concrete's sustainable alternative, namely alkali-activated concrete (AAC), requires rigorous experimental investigations. Since the AAC has emerged as a preferred material for modular or precast structural members, the investigations on the fire resistance and response of AAC as the modular walls and partition may be worth exploring. In the present article, the experimental study of the effects of direct fire on the surfaces of the modular prototype AAC panels has been discussed. The performance criteria of the AAC prototype panels conforming to the IS: 3809-1979 has been evaluated under the varying time durations of fire exposure. The observation values, namely time duration, fire load temperature, the thermal conductivity of panels, mechanical strength before and after fire exposure, and the spalling attributes, were recorded. The test results revealed an encouraging response by the AAC panels under the fire exposure. The AAC panels remained nearly unaffected from any significant surface deterioration, spalling, or cracking even for extended time duration of fire exposure. The panels demonstrated excellent resistance to thermal conductivity also. Similarly, the residual mechanical strength of the panels was found higher than that of the conventional concrete.
