Test To Check Consistency Of Cement

Posted in Civil Engineering Tests | Email This Post Email This Post

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.
Apparatus – Vicat apparatus conforming to IS: 5513 – 1976, Balance, whose permissible variation at a load of 1000g should be +1.0g, Gauging trowel conforming to IS: 10086 – 1982.

Procedure to determine consistency of cement
i) Weigh approximately 400g of cement and mix it with a weighed quantity of water. The time of gauging should be between 3 to 5 minutes.
ii) Fill the Vicat mould with paste and level it with a trowel.
iii) Lower the plunger gently till it touches the cement surface.
iv) Release the plunger allowing it to sink into the paste.
v) Note the reading on the gauge.
vi) Repeat the above procedure taking fresh samples of cement and different quantities of water until the reading on the gauge is 5 to 7mm.

Reporting of Results
Express the amount of water as a percentage of the weight of dry cement to the first place of decimal.

    hello..
    sir
    thank u lat

    THANK U SIR

    can i plz get info y only .8%water is used check the consistency of cement?

  • shamsher alam November 28, 2009 at 7:20 am

    what is the physical significance of normal consistency of cement?

  • james m December 2, 2009 at 2:57 pm

    Hi sir .
    can i kindly know how the consistency is constant.

  • RRaghu January 27, 2010 at 12:28 pm

    hello sir/madam,
    why only 400gms of cement is taken for the consistancy test and why not more or less?

    • Nalini August 3, 2010 at 2:03 am

      Bcoz the vicat apparatus has a mould whose volume can fill by 400gm.

    Hi sir,

    THANK U SIR!!

  • Abiodun May 21, 2010 at 4:43 pm

    Does this consistency check procedure also applies to rapid hardening portland cement?

  • abhishek August 5, 2010 at 2:03 am

    from book CONCRETE TECHNOLOGY wrtten by M.S. Shetty. publication by S.Chand
    penetration in standard consistancy test is given 33-35 mm. and here u give value 5-7mm . so clear my confusion.

    • admin August 5, 2010 at 9:23 am

      That value would be from top, here the value is from bottom. Total height of apparatus = 40mm

    gud day!
    can you please provide discussions about consistency of standard cement paste..
    thanks…

  • karena August 9, 2010 at 9:48 am

    gud nite!!!!!can you give me conclusion n more discussion about consistency of standard cement paste????

  • mand August 17, 2010 at 6:10 am

    1. what are the other alternative equipment that can be used in determining the normal consistency of Cement?
    2. pls provide ASTM standard for normal consistency and also standards for different design mixture of concrete.
    Tnx!

  • kuljeet August 18, 2010 at 10:18 am

    what would be the percautions required for the test?
