摘　　要：以石膏胶凝材料为主,辅以矿渣,测试不同添加组分(棉花秸秆皮纤维、EPS颗粒和硅酸盐水泥)和不同养护条件对复合材料力学性能的影响。结果表明,棉花秸秆皮纤维具有改善EPS颗粒与复合材料粘结的性能;EPS颗粒粒径大小和掺量对复合材料抗压强度有一定的影响;硅酸盐水泥掺量越高,复合材料力学性能越好;高温蒸汽养护较自然养护条件试样力学性能和软化系数明显提高。In this paper＇when gypsum plaster is given priority to,supplemented with slag particles and different additives （cotton straw skin fiber, EPS particle and Portland cement） under different curing conditions,the influence on the compound mate- rial mechanieal performance is tested. The experimental results show that the cotton straw skin fiber is to improve the performance of the EPS particles and composite binder： Size and dosage of EPS particle have effects on the compressive strength of the com- posite;The more amount of silicate cement composite is added,the better mechanical properties of the straw fiber composite mate- rial：Comparing with under the natural curing conditions,sample mechanical performance and softening coefficient increase signifi- cantly under the high temperature steam curing.
