What is the size of plunger in Vicat Apparatus?
10 mm diameter
Vicat’s apparatus consists of an arrangement to hold the plunger of 10 mm diameter and two other needles which are made to freely fall into a mold filled with the cement paste and the amount of penetration of the needles of plunder can be noted using the vertical graduations from 0 mm to 50 mm.
What is plunger in Vicat Apparatus?
The apparatus consists of a frame bearing a movable plunger of 300 grams weight. The Plunger is 10 mm diameter at one end and is fitted with a removable 1 mm diameter needle at the other end. The plunger is reversible and carries an indicator which moves over the scale graduated in millimeters.
What is Vicat test?
One of the most common ways to assess cement consistency is with a Vicat apparatus. This machine is used to determine the standard consistency of a cement paste, as well as its initial and final setting time. To establish a paste’s standard consistency, a Vicat plunger is used.
How is Vicat Apparatus used?
Vicat Apparatus is Used For:- Vicat apparatus is generally used to determine the required quantity of water to produce a cement paste of normal or standard consistency. It is also used in the tests for initial setting time of cement or concrete and final setting time of cement or concrete.

What is the height of slump cone?
The Slump Cone apparatus for conducting the slump test essentially consists of a metallic mould in the form of a frustum of a cone having the internal dimensions as : Bottom diameter : 20 cm, Top diameter : 10 cm, Height : 30 cm and the thickness of the metallic sheet for the mould should not be thinner than 1.6 mm.
How do you use a Vicat needle?
Initial setting time of Cement: Fill out the Vicat mould and finish its surface. A test block is now prepared for the test. Again, place the mould on a non-porous plate under the rod and needle. Lower the needle to touch the surface and release quickly and let it penetrate through the paste.
What is Vicat needle?
The Vicat test is used for testing materials that have no real melting points. The main principle is that it measures the temperature at which a flat ended needle is able to penetrate the sample. This is known as the softening point of the material.
