To validate the above conclusion, a series of mixture tests were performed and different samples were made by mixing each of three kinds of nature silt and the nature clay with different mixture ratio. The liquid-plastic limits of all the samples, in which the clay particles content were between the nature silt and the nature clay, were attained using the combined test method. The results showed that the lowest clay particles content of the silt, when it was suitable with the combined test method, is 12% to 15% with little differences. If the point of 3～4mm depth of penetration of fall cone exist, and the loglog relationship between the depth of penetration of fall cone and the water content of all the points were clearly linear, it could be concluded that the clay particles content of the sample is over the lowest value when the combined test was suitable.

3其后为了进一步验证所得结论，针对三种粉土，分别与一种黏粒含量较大的天然黏土进行多种组合的配比试验，配比后的土样其黏粒含量均介于原粉土与原黏土之间，并对各种配比后土样进行联合测定法确定液、塑限的试验研究，得出各种土对联合测定法适用的最低黏粒含量限值因粒径组成不同、矿物组成不同等因素，存在微小差异，在12%到15%之间；当圆锥下沉深度在3～4mm之间的试验点存在，且与其他试验点之间能形成良好的双对数直线关系，即认为土中黏粒含量超过该土对联合测定法适用的最低限值，联合测定法适用。
