Abstract	This study deals with the effects of carbon dioxide (CO2)-air concentration in the rapid curing method on the properties of cement-bonded particleboard manufactured using conventional cold pressing as the setting method. The hydration of cement was examined using X-ray diffractometry, thermal gravimetry, and scanning electron microscopy. The results are as follows: (1) The properties of CO2-cured boards improved with increasing CO2 concentration. When 10% or 20% CO2 was applied for 10 min of curing time, the properties of the CO2-cured boards were comparable to those obtained by conventional 2-week curing. (2) The hydration process of cement could be accelerated within several minutes using CO2 curing, even with a low concentration of 10%–20% CO2; a reduction in calcium hydroxide was observed followed by rapid formation of calcium carbonate.
