Testing cement for quality and reliability
The initial setting time is defined as the time taken for the Vicat needle to be able to penetrate the paste in the mould to a depth of 5mm. The final setting time is the time taken for the cement paste to harden sufficiently such that the Vicat needle cannot penetrate the cement paste in the mould and leaves no mark on the surface of the specimen.
