Title Statement Utilization of river red gum (Eucalyptus camaldulensis Dehnh.) for wood wool cement board by Dwight A. Eusebio, Edgardo M. Villena, Edgardo F. Funtanillaa Physical Description 1-14 graphs, tables Summary, Etc.      Laboratory size (30 x 30 cm) wood wool cement boards (WWCB) at three density levels (0 .60, 0 .80 and 1.00 g/cm3) and thickness of 12 mm were produced using river red gum (Eucalyptus camaldulensis Dehnh.) wood as raw material. The effects of soaking the wood excelsior in water prior to mixing with cement, wood/cement ratio and accelerator on board properties were determined. The boards' modulus of rupture (MOR), modulus of elasticity (MOE) and nail-head-pull through (NHPT), as well as thickness swelling (TS) and water absorption (WA) after 24-hr water immersion, were likewise determined.      MOR, MOE and NHPT increased with increasing board density. The highest MOR and MOE were obtained from boards with the most cement, i.e., wood/cement ratio of 30/70 while the opposite was observed for NHPT. As expected, WA and TS decreased as cement content increased. Boards with unsoaked excelsior exhibited higher WA and TS properties, meaning poorer dimensional stability, than boards with soaked excelsior at 50/50 and 40/60 wood/cement ratios.
