摘要
从新机场项目取土样,烘干粉碎后过筛制成标准样,在确保环境温度一致、分散剂一致、单次试验用量一致的情况下,分别使用密度计法和移液管法做对比试验,对试验结果的黏粒含量数据作出对比和分析,得出在相同条件下,移液管法和密度计法颗粒分析试验结果基本接近。通过比较两种试验方法所采用的仪器设备和操作过程,发现移液管法误差相对较小,对悬液搅动小,具有较多的优点。
Make standand samples after drying,crushing and sieving the samples which are from the new airport project.In the condition of the same ambient temperature,the same dispersant,and the same single test dose,make contrast experiments by using density meter and pipette method,respectively.According to compare the results by using the two different methods,the content of clay of both methods are nearly equal.It is proved that pipette method has more advantages on smaller error and slighter agitation to suspension.
