Abstract

The effects of wood and non-wood fibres reinforcement on the properties of Plaster of Paris were evaluated. The woody and non woody residues were varied in 10, 20, 30, 40, and 50 % of the whole mix while the Plaster of Paris used was in the ratio 100 (control), 90, 80, 70, 60, and 50 %. The mean density of the composite produced is 3250 kg/m3. The mean thickness swelling and water absorption after 2 and 24 hours were 0.84 % and 0.88 %, and 13.8 % and 16.2 % respectively. The MOR and MOE increased with increase in fibre content hence the composite is suitable for indoor applications.

木与非木石膏复合天花板的物理力学性能

评价了木纤维和非木纤维增强剂对巴黎石膏性能的影响。木质和非木质残留物在整个混合物中的比例为10%、20%、30%、40%和50%，而所用的巴黎灰泥的比例为100（对照）、90%、80%、70%、60%和50%。所生产的复合材料的平均密度为3250 kg/m3。2小时和24小时后的平均厚度溶胀率和吸水率分别为0.84%和0.88%，13.8%和16.2%。MOR和MOE随着纤维含量的增加而增加，因此该复合材料适用于室内应用。
