Vicat's Apparatus and Its Use
Vicat's apparatus is a device used to determine the **consistency** and setting time of cement. It helps assess the water requirement for cement paste to achieve a standard consistency, as well as the initial and final setting times of cement.
Analyzing the Given Options:
1. Fineness Test:
- The fineness of cement is determined using methods like sieving or air-permeability tests.
2. Consistency Test:
- The Vicat's apparatus is primarily used to determine the standard consistency of cement paste. Standard consistency is the amount of water required to produce a cement paste of standard viscosity, which is critical in ensuring proper hydration and strength.
3. Compressive Strength Test:
- The compressive strength of cement is measured using cubes of cement-sand mortar, which are tested in a compression testing machine.
4. Soundness Test:
- The soundness of cement is determined using devices like the Le Chatelier apparatus or autoclave.
