摘要

进行了一项调查，以确定最佳水灰比为当地生产的波特兰水泥用于木材复合材料。采用相容性因子法(CA)评价了预处理和氯化钙(CaCl2)对两种藤(菖蒲和Lacosperma secundiflorum)与水泥相容性的影响。最佳水灰比为0.45。两种藤本植物与水泥的相容性较好。CA因子随CaCl2浓度的增加而增加(0 ~ 3%浓度下，黑松草的CA因子为65.2% ~ 101.5%，次花莲的CA因子为71.2% ~ 103.5%)。去除硅化表皮(预处理)对木犀草与水泥相容性的影响显著(P≤0.05)。此外，由于解剖结构和其他方面的差异，Lacosperma物种的颗粒比Calamus物种的颗粒更能与水泥相容。关键词:藤，氯化钙，水泥相容性

Compatibility of Calamus deerratus and Lacosperma secundiflorum Rattan Particles with Ordinary Portland Cement

An investigation was conducted to determine the optimum water to cement ratio for a locally manufactured Portland cement for use in wood composites. The effects of pre-processing and calcium chloride (CaCl2) on the compatibility of two rattan canes (Calamus deerratus and Lacosperma secundiflorum) with cement were also assessed using the compatibility factor (CA) approach. An optimum water: cement ratio of 0.45 was obtained. Generally the two rattan species were compatible with cement. The CA factors increased with increasing levels of CaCl2 concentration (65.2% to 101.5% for C. deerratus and 71.2% to 103.5% for L. secundiflorum at 0 to 3% concentrations). Removal of the silified epidermis (pre-processing) had more significant effect (P ≤ 0.05) on the compatibility of C. deerratus with cement than in the L. secundiflorum species. Also, the particles of the Lacosperma species were more compatible with cement than those of the Calamus species probably due to the anatomy and other variations in the two species. Keywords: Rattan, Calcium chloride, cement compatibility
