Method of Preparing Artificial Lightweight Aggregate
The present invention relates to a method of manufacturing artificial lightweight aggregate formed of a ceramic oxide raw material and, more specifically, to a method of manufacturing artificial lightweight aggregate, in which iron and carbon are added to a raw material, and the resultant raw material is molded at the molding density of 1.3 g/cm^3 or higher, dried and pre-heated at a temperature of up to 600°C for 60 to 120 minutes, calcined at a foaming activation temperature of 600°C for 5 to 20 minutes, and sintered at a foaming activation temperature of 1,000 to 1,250°C for 20 minutes or less, such that the foaming effect of the lightweight aggregate is increased, a fusion phenomenon is prevented by lowering the foaming activation temperature by 50 to 100°C, and energy efficiency is increased.
