What are Different Tests for Concrete Quality Check?

3. Setting Time. The action of changing mixed cement from a fluid state to a solid state is called "Setting of Cement". Initial Setting Time is defined as the period elapsing between the time when water is added to the cement and the time at which the needle of 1 mm square section fails to pierce the test block to a depth of about 5 mm from the bottom of the mold.

Test To Check Consistency Of Cement - Civil Engineering

CONSISTENCY The basic aim is to find out the water content required to produce a cement paste of standard consistency as specified by the IS: 4031 (Part 4) – 1988. The principle is that standard consistency of cement is that consistency at which the Vicat plunger penetrates to a point 5-7mm from the bottom of Vicat mould.
