A viscometer is used to determine the viscosity of which materials?

• A. The viscosity of slurries, fresh concrete, and liquids
• B. The density of solids
• C. The color of liquids
• D. The pH of solutions in a mixture

Answer: (A)

Viscosity is the measure of a fluid’s resistance to flow. A viscometer is designed to quantify that resistance, which is why it’s used for materials like slurries, fresh concrete, and other liquids where how easily the material flows affects workability and placement. In concrete and similar mixtures, knowing viscosity helps ensure the material can be pumped and spread properly. The other properties—density, color, and pH—are measured with different instruments or tests, not with a viscometer.
