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.
i want various method testing of cement with procedure & details as well as mehod of testing of aggregate with procedure
in this test the expansion should be limited with range of ———-
how we carry out the strengh test of cement.
In the soundness test you have not mentioned the range of expansion of cement please mention it sir
Kindly mention range of expansion of cement paste in soundness test.
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?
