摘要：
For the purpose of determining a weight concentration of a clay material in a porous medium sample, a specific active surface area of the clay material and an initial specific active surface area of the porous sample are measured. A water solution of the clay material is pumped through the sample and a specific active surface area of the sample of the porous medium is measured after the pumping. Then, the weight concentration of the clay material is calculated.
