SOUNDNESS
Soundness of cement is determined by Le-Chatelier method as per IS: 4031 (Part 3) – 1988.
Apparatus – The apparatus for conducting the Le-Chatelier test should conform to IS: 5514 – 1969
Balance, whose permissible variation at a load of 1000g should be +1.0g and Water bath.

Procedure to determine soundness of cement

i) Place the mould on a glass sheet and fill it with the cement paste formed by gauging cement with 0.78 times the water required to give a paste of standard consistency.

ii) Cover the mould with another piece of glass sheet, place a small weight on this covering glass sheet and immediately submerge the whole assembly in water at a temperature of 27 ± 2oC and keep it there for 24hrs.

iii) Measure the distance separating the indicator points to the nearest 0.5mm (say d1 ).

iv) Submerge the mould again in water at the temperature prescribed above. Bring the water to boiling point in 25 to 30 minutes and keep it boiling for 3hrs.

v) Remove the mould from the water, allow it to cool and measure the distance between the indicator points (say d2 ).

vi) (d2 – d1 ) represents the expansion of cement.

    materials very brief and need to be expanded especially details of experiments. on the whole the materials are good.

      pls share soundness test on cement procedure by autoclave method

  • prashant July 30, 2009 at 5:28 pm

    i want various method testing of cement with procedure & details as well as mehod of testing of aggregate with procedure

  • parveen sharma October 30, 2009 at 1:43 am

    in this test the expansion should be limited with range of ———-

    • bdc November 25, 2011 at 9:24 am

      0 to 10 mm

  • nishimwe ngabo leonidas November 2, 2009 at 7:55 am

    how we carry out the strengh test of cement.

  • Kishore March 20, 2010 at 3:29 am

    In the soundness test you have not mentioned the range of expansion of cement please mention it sir

  • Mahesh May 26, 2010 at 10:26 pm

    Kindly mention range of expansion of cement paste in soundness test.

  • sasanka August 18, 2010 at 1:53 am

    i have read all this exaplained in google. but here exaplain that soundness test conforms whether there will be any volume change in future or not or whether it will disintegrate or not. Can you any body exaplain me the actualy meaning of soundness test for cement and defination of soundness test?

    • sanchit July 22, 2011 at 1:29 pm

      hi, soundness of cement means that cement should not go any appreciable change in volume or simply u can say it should not expand..that is the soundness test to check the expansion of cemnt.

    thanks alot, i am a student of civil engr. level 100 i need some civ engr softwares.

  • saravanan November 29, 2010 at 6:45 am

    please give autoclave test procedure as possible.

  • satish kumar December 22, 2010 at 3:59 am

    what is the practical significance of this soundness test???
    what if soundness is more..???

    • sanchit July 22, 2011 at 1:31 pm

      if the soundness is more than it will cause serious difficulties in durability of structure…

  • shaker February 15, 2011 at 9:21 am

    please give the method to prepare sample for autoclave that is the ratio of water and cement and curing of sample before putting it in the autoclave

  • woliti waswa emmanuel April 6, 2011 at 8:43 am

    please is it possible to have a video explanation of this test

  • Karam November 15, 2011 at 1:21 pm

    What is the range of soundness

    • Subhajit March 6, 2012 at 11:17 am

      I think it is not more than 10%

  • GOPAL BASAK November 18, 2011 at 1:31 am

    total IS 4031

  • sarhang December 11, 2011 at 4:40 pm

    what is the significance of this test?

  • hafiz December 22, 2011 at 5:44 am

    why we need leave the cement 24 hour before we measured the expansion
    and half and hour for another reading…?

  • vijayabaskaran January 19, 2012 at 10:39 am

    what do we mean by indicator points in soundess test? i don’t understand

  • Ezra January 30, 2012 at 4:51 am

    what is soundness of cement and what is its purposes?

  • Subhajit March 6, 2012 at 11:13 am

    how can i calculate the quantity of cao in cement

  • akbar ali June 15, 2012 at 2:00 am

    The methodology explained is good but need more explanation specially for the practitioner who a actually involved in testing.
