In this study, the fireproof performance of high-density ALC floor panels was investigated. High-density ALC panels designed in accordance with the allowable stress under the design condition of 2,500mm less length, 3,500N/m2 less live load and 100mm more thickness have the fireproof performance which is necessary for Building Standards Act as a floor panel of fireproof construction. The fireproof performance of the floor structure using the high-density ALC panel can be evaluated by the parameters of the maximum load, the maximum length and the lowest thickness obtained by the fireproof test.

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.

Carbonation of ALC panels progresses simultaneously throughout the whole section. Even with ceramic tiles laid on one side of the panel, ALC is carbonated to the back of the tiles by CO2 penetration from the other side. In this research, tiled ALC panels were subjected to accelerated carbonation followed by bond strength testing between ALC and tiling. As a result, it was found that carbonation of ALC does not directly cause tile spalling up to a carbonation degree of 89%.

This paper reports on the strength of 100 mm-thick ALC subjected to accelerated carbonation (0.3 vol.% C02). The flexural strength and elastic modulus of ALC under accelerated carbonation retain the initial levels up to a carbonation progression degree (CPD) of around 30%, but decrease thereafter as the CPD increases. The compressive strength tends to exceed the initial level at an early stage of accelerated carbonation, but after the CPD exceeds 45%, the strength decreases as the CPD increases. The declining trends of the residual ratios of the flexural strength, compressive strength, and elastic modulus are linearly related to the CPD.

From the standpoint of the maintenance and management of ALC-buildings, the ability of ALC panel to be reused after being subjected to fire is likely to become an important issue. In the research described here, the adhesion in tension, compressive strength and bending strength of ALC panel after heating was studied. Moreover, the effect of strength recovery by spreading materials were studied. As a result, the effect of the strength recovery was confirmed.
