    Notes: Summary Wood-cement panels have commanded renewed interest during the last decade because of their potential application in the building industry. Several methods to classify wood of various species regarding its compatibility with cement have been established in the literature based on hydration measurements in Dewar flasks. These ranking methods lack consistency in the classification of species because the hydration conditions vary among laboratories. Three techniques for evaluating wood-cement compatibility were established and compared. The best technique is based on a wood-cement compatibility factor which is the ratio of the area under the wood-cement hydration heat rate curve to that of neat cement. The area is calculated on 24-h basis starting from the initial cement set time. This area ratio method ranks species over a 100% scale and accounts well for species that are totally incompatible.

    The effect of alkylene oxides, furan resin and vinylpyrrolidinone on wood dimensional stability (1984)
    Springer
    Wood science and technology 18 (1984), S. 225-240

    ISSN: 1432-5225

    Notes: Summary The effect of propylene oxide, butylene oxide, furan resin, and vinylpyrrolidinone in controlling wood dimensional stability have been examined. Wood in the green or ovendry condition was treated with various chemicals using a vacuum-pressure procedure. Treated specimens were tested for tangential swelling, moisture gain, and changes in sorption hysteresis. Results indicate that propylene oxide and butylene oxide enhanced with the crosslinking agent trimethylol propane trimethacrylate, applied to ovendry wood were the most efficient chemical treatments in controlling hygroscopic dimensional changes. The sorption behavior of treated wood as depicted by the ratios of sorption was “very favorable” in most instances. In the case of treatments with furan resin, ratios of sorption were improved from 25 to 100 percent as compared to those of untreated wood.
