EVALUATION OF THE THERMAL PROPERTIES OF ALC SUBJECTED TO ACCELERATED CARBONATION

Abstract

This study deals with the thermal properties of ALC panels subjected to accelerated carbonation. Difference in the thermal conductivity of ALC subjected to accelerated carbonation was marginal, scarcely affecting its heat insulation design values. Also, up to a degree of accelerated carbonation of 70%, the temperatures within ALC panels including steel reinforcement were comparable to those of uncarbonated ALC panels during fire resistance testing. Accelerated carbonation therefore causes no appreciable difference in the heat- and flame-shielding performance of ALC panels evaluated by fire resistance testing.
