Determining method for liquid limit, plastic limit and plasticity index, involves screening in two porous washers on extractor membrane, where water is poured on washers and is left for suction

摘要

The method involves screening in two porous washers on an extractor membrane. The water is poured on the washers and is left for suction. The washers are put in airtight containers for two days and are introduced in extractor in one day. The pressure to measure humidity portions lies in a certain range. The weight of material has sieve number 40 American Society for Testing and Materials passing through the sieve number 200 American Society for Testing and Materials.
