To provide a method for manufacturing ALC panels allowing prevention of discoloration without equipment cost or time, and to provide the ALC panels and semi-cured bodies.
The method for manufacturing the ALC panels includes: a casting process for casting, into a form disposed with reinforcement bars, raw material slurry made by adding water to a solid component composed of siliceous raw material and calcareous raw material as main raw materials and kneading it; a semi-cured body manufacturing process for manufacturing the semi-cured body by curing the raw material slurry; a cutting process for obtaining a plurality of panel-like semi-cured bodies by cutting the semi-cured body; and a curing process for autoclave curing of the plurality of panel-like semi-cured bodies. One or more glycerins selected from the group consisting of glycerin, diglycerin and polyglycerin having polymerization degree of 3 or higher are sprayed to at least an end face out of surfaces of the panel-like semi-cured material.
