摘要: 玄武岩残积红土(HCP2e)性质特殊,其粒度组成复杂,目前尚未有专门的研究成果,严重制约了红土级配组成及分类属性的系统研究.本文对4种分散剂对玄武岩残积红土(HCP2e)进行对比试验,讨论分散剂种类和浓度对玄武岩残积红土(HCP2e)团粒体的分散效果,以此获得其粒度组成特征值.试验结果表明,浓度为6%的六偏磷酸钠使玄武岩残积红土达到最佳分散效果,并获得了相对应的粒度组成特征值.Abstract: The quality of basalt eluvial laterite (HCP2 e) is special,besides,its granularity composition is also complex and there is no special research results at present.Therefore,the research of the graduation,composition and classification of laterite is restricted.The article chose four kinds of dispersants to have study on basalt eluvial laterite.(HCP2e)The effect of different dispersant on different concentration and on basalt eluvial laterite (HCP2e)was discussed and to obtain granularity composition eigenvalue under different dispersant and concentration.The result show that the calgon that has 6 percent concentration can achieve the best dispersion effect of basalt eluvial laterite and obtain corresponding granularity composition eigenvalue.The results of this research has great guiding significance on the analysis of granularity and the systematic study on engineering properties.
