Abstract

This study dealt with the effects of a curing method that uses gaseous and supercritical CO2. Its effects on the properties of oil palm fronds cement-bonded board manufactured by the conventional cold-press setting method were recorded. The effect of MgCl2 as an accelerator of cement setting was also investigated. The hydration of cement was examined using X-ray diffractometry, thermal gravimetry, and scanning electron microscopy. The results are as follows. (1) High-performance cement-bonded boards made from oil palm fronds were successfully manufactured using the CO2 curing method. (2) The curing method using either gaseous or supercritical CO2 resulted in accelerated curing of cement (within several minutes). Accelerated formation of the hydration products (e.g., calcium carbonate and calcium silicate) is the main reason for the high strength of CO2-cured boards. (3) The CO2 curing technology does not require setting accelerators, which cause a decrease in the dimensional stability of cement-bonded board.
