The computerized pattern recognition for distinction of resistance to water of magnesiumoxychloride cement doped with various additives has been done by using compositions and 13additives as the characteristic parameters and by using resistance to water of the cement ascriterion,which is determined by the changes in compressive strength of magnesium oxychloridecement measured on the same samples hardening for 28 days in air and immersing in waterfor 3 months.The distinction has been realized in both high-dimensional and two-dimensionalspace.The result shows that the training-points with different water-resistant properties ofthe cement are clearly located in two regions in two-dimensional space.The water-resistantproperties of 8 samples are predicted by using the distribution rule,which consists with theexperimental results.

以镁水泥组分及13种添加剂为特征参数,试样在空气中养护28天与水中浸泡一定周期的强度相对变化值表征镁水泥的耐水性能,应用模式识别法对掺入各种添加剂的镁水泥就其耐水性能的优劣在高维空间进行分类,并将高维空间中的点集压缩到二维空间,结果表明,不同耐水性能的训练点分别落入二维空间的不同区域.利用这个分布规律对耐水性能未知的八组镁水泥试样进行了耐水性能的预报.实验数据与预报结果一致.

The enhancement of interface bonding between cement and polymer and the structural reticulation of the water soluble polymer are proposed to minimize the shortening of the mechanical properties of macro defect free(MDF)cement based composites at high relative humidity The MDF composites incorporated with various cross coupling agents were studied. The results show that not only can the MDF composites modified with small amounts of cross coupling agent improve the mechanical properties,but modify the water resistance of MDF composites compared to the original one In the meantime if the water resistant material such as fine powder of α alumina was used to substitute for the unreacted cement grains in the MDF composites,a more efficient improvement of water resistance would be obtained The loss in flexural strength of the MDF composites after 90 days of water immersion decreased from 62% before unmodifying to 15% after modifying

聚合物—水泥界面粘结的增强以及水溶性聚合物结构的网络化已被提出可以减小无宏观缺陷 (MDF)水泥基复合材料在高相对湿度下力学性能的倒缩。通过对各种不同偶联剂掺入MDF水泥基复合材料的试验研究发现 ,微量偶联剂不仅可提高复合材料的力学性能 ,更为重要的是改善了复合材料的抗水性。若同时采用水惰性的α Al2 O3微细粉替代MDF水泥基复合材料中的未反应水泥组分 ,可以进一步提高复合材料的抗水性 ,其在水中浸泡 90d的抗折强度损失将由未改性前的 6 2 %下降到改性后的 1 5 %。
