plasticity index การใช้

Plasticity index of A-7-6 subgroup is greater than LL-30
Note ( 1 ) : Plasticity index of A-7-5 subgroup is equal to or less than the LL-30.
Greenwood and Williamson defined a dimensionless parameter \ Psi called the "'plasticity index "'that could be used to determine whether contact would be elastic or plastic.
These objects are made from substances such as glass, alumina, zirconia, silica, affinity for water and a lower plasticity index than clay, requiring organic additives in the stages before sintering.
The "'Plasticity Index "'of a particular soil specimen is defined as the difference between the Liquid Limit and the Plastic Limit of the specimen; it is an indicator of how much water the soil particles in the specimen can absorb, and correlates with many engineering properties.
