Abstract

ALC panels become the building members with necessary strength and durability by the autoclave cure. Autoclave cure of ALC takes approximately 10 h under the temperature of 180℃ and saturated steam pressure of 1MPa. It is thought that strain difference between ALC and reinforcing bar, as a result of temperature change, causes the internal stress in ALC panels. This study was conducted to clarify the existence of the internal stress in ALC panels.
