摘要
实验研究了α－Ａｌ_Ｏ和ＳｉＯ_２混合超细粉与分散剂ＦＤＮ对高强度耐磨浇注料施工和物理性能的影响。试验结果表明：α－Ａｌ_２Ｏ_３和ＳｉＯ_２混合超细粉加入５％～７％时，浇注料的施工和理化性能最佳；加入适量的ＦＤＮ，其降水率可达２０％。
The effect of mixed ultra fine powder of α-Al2O3 and SiO2 and dispersant FDN on the workability and physical properties of high strength and abrasion-proof castable,the result has showed that adding 5%～7% mixed ultra fine powder is optimum for the properties.Suitable amount of FDN makes water-reduction rate reach at least 20%.
