摘　　要：采用憎水性酚醛树脂代替亲水性聚合物,从根本上解决了无宏观缺陷(MDF)水泥的耐水性问题.结果表明,高铝水泥/酚醛树脂MDF水泥具有优良的耐水性.Macro-defect-free（MDF） cement based materials is a new class of high-strength materials, but the poor water resistant performance cumber the area of its application. For this purpose, the alcohol-soluble phenolic resin precursor and high alumina cement were used in this study. Test results show that water only immerged the surface of MDF cement, so the flexural strength receded 6.8% in water in 1 year.
