耐水氯氧镁水泥/玻璃纤维复合材料的研制

摘要

通过添加外加剂,对氯氧镁水泥进行改性,制备耐水氯氧镁水泥/玻璃纤维复合材料,实验结果表明:单一外加剂在氯氧镁水泥中有最佳掺量；磷酸的加入,可以增加氯氧镁水泥/玻璃纤维复合材料的耐水性能；减水剂与FeSO4的交互作用显著,当减水剂用量为0.25％、FeSO4用量为1.5％时复合材料的强度最高,耐水性能良好；通过外加剂的复配,可以制备耐水的氯氧镁水泥/玻璃纤维复合材料.%Magnesium oxychloride cement was modified with additive,and the water resistant magnesium oxychloride cement/glass fiber composite materials were prepared.Test results showed that:a single admixture in magnesium oxychloride cement had the best dosage; the properties of the magnesium oxychloride cement/glass fiber composite material could be increased with phosphoric acid; the interaction of water reducing agent and FeSO4 was significant,when superplasticizer dosage was 0.25％ and FeSO4 dosage was 1.5％,the intensity of composite material was the highest,and water resistance was very well.The high strength,water resistance magnesium oxychloride cement/glass fiber composite material the could be prepared with additive compound
