Standard Consistency of Cement

The test conducted by Vicat Apparatus is for

• Fineness

• compressive strength

• Consistency

• Soundness

The Diameter of the Vicat plunger is 10 mm and its length varies from

• 2 to 5 mm

• 5 to 10 mm

• 10 to 20 mm

• 40 to 50 mm

If 300 gms of water is required to produce 375 gms of cement paste of normal consistency, the percentage of water is

• 25%

• 125%

• 80%

• 175%

The Consistency test is performed to find

• The correct water cement ratio

• The fineness of cement

• The compressive strength

• Tensile strength

The Initial setting time of OPC Should not be less than

• 15 min

• 30 min

• 45 min

• 1 hr.

When water is added into the cement

• Impurities are washed out

• Heat is generated

• Heat is Absorbed

• Chemical Reaction start

Vicat Apparatus is used to determine

• Initial Setting time of cement

• final setting time of cement

• standard consistency of cement

• all of the above

In Vicat Apparatus for consistency of standard cement paste the amount of water mixed is expressed as a percentage by weight of dry cement, this is usually

• 75%

• 50%

• 30%

• 12%
