By using rheological measurements, a quantitative modeling method, as well as fitting of data, the main rheological properties of potassium silicate solutions (PSS) were determined. The results show that the steady state shear viscosities of PSS rapidly increase with concentration in the tested domain and molar ratios. However, they decrease with temperature from 15 to 60 °C. The newly improved Krieger–Dougherty expression, which inherited the principal properties of both the Krieger–Dougherty and the Kaminsky equations, can describe the mea...
