A kaolinite group- these show minimum volume change during moisture variation.

What is mite group and in which topic this group is considers?

Sayandip Basak said: (May 31, 2015)  
Kaolinite or China Clay is used to make pots. It causes no swelling and no shrinkage. So option A is the answer.

Ammu said: (Sep 22, 2015)  
Please give the correct options.

Swar said: (Sep 25, 2015)  
Answer: Kaolinite, mite is organic soil.

Laxmi said: (Oct 3, 2015)  
What do you mean by mite group?

Abhi said: (Oct 4, 2015)  
Illite also shows no swelling.

Ankush Saklani said: (May 22, 2016)  
Illite group is also the correct answer, which is not in the given option.

Ankush said: (Jul 3, 2016)  
Kaolinite is not swell. So answer is Kaolinite.

Inayath said: (Oct 25, 2016)  
Can anyone say which one is correct?

Samm said: (Nov 13, 2016)  
Illite is a clay mineral in mite group does not swell.

Baloch said: (Dec 29, 2016)  
It should be an Illite, not a Mite group.

Akash said: (Jan 6, 2017)  
Kaolinite - No swelling.

Illite or mite - medium swelling.

Montmori - High swelling so the answer is A.

Gunjan said: (Jan 18, 2017)  
Can anyone say which one is correct answer?

Dipen Tilva said: (Jan 19, 2017)  
Kaolinite has a low shrink"swell capacity.

Vermiculite medium shrink-swell capacity.

Illite or mite is responsible for the absence of swelling.

Montmori - High swelling.

So answer. B is correct.

Montubhai Talaviya said: (Feb 6, 2017)  
Please give the right answer with the correct explanation.

Sheenam said: (Apr 15, 2017)  
It should be Kaolinite.

Amit said: (Jun 12, 2017)  
Illite give medium swelling.

Sharmila said: (Jun 28, 2017)  
Kaolinite will have no shrinkage and swelling effect.

Abhijeet said: (Aug 6, 2017)  
Swelling relation.

Montmorilonite > illite > kaolinite.

Sipun said: (Sep 14, 2017)  
Kalonite clays allowed less water so shrinkage and swelling is less.

Sumeet Kulkarni said: (Sep 26, 2017)  
Kaolinite has gibbsite sheets with aluminium their centre. Since hydrogen bond is involved it is extremely difficult to separate the layers, therefore kaolinite is stable and water is unable to penetrate b/w the layers hence kaolinite shows no swelling when wetting.

Kaolinite - no swelling ( China clay),
Illite - little swelling,
Montmorillonite - high swelling (B.C Soil).

So answer for given question must be A.

Shubham said: (Dec 23, 2017)  
In illite_ The space between individual clay crystals is occupied by poorly hydrated potassium cations which are responsible for the absence of swelling.

Roy said: (Jan 3, 2018)  
Yes, A is correct answer.

Vidhi said: (Feb 20, 2018)  
Mite is an organic soil & act as a decomposer in soil & Kaolinite behaves as a no swelling properties so the correct answer is Kaolinite.

Sachin said: (Mar 11, 2018)  
Kaolinite is stable mineral causes no dwelling & shrinkage. So the answer should be kaolinite.

Naveen Gibbs said: (Mar 14, 2018)  
The answer must be kaolinite.

Mabood said: (Jun 4, 2018)  
Please give the correct option with explain.

Mayur said: (Jul 29, 2018)  
Kaolinite is very stable group of soil which does not allow any shrinkage and swelling effect. China clay is best example of this group hence correct answer is option "A".

Raihan Kaizen said: (Sep 10, 2018)  
Kaolinite is nonexpendable, because of its strong hydrogen bond. So, the right answer is A.

Bijay Tandon said: (Oct 11, 2018)  
A is the correct answer because of no swelling & shrinkage.

Rupesh said: (Mar 6, 2019)  
Kaolinite a highly stable 1:1 (silica: gibbsite) mineral which is non-swelling with a relatively small surface area, and low adsorptive capacity.

So, the correct answer is Kaolinite.

Sathish said: (Jun 8, 2019)  
Kaolinite group is the correct answer.

Sahil Rathod said: (Oct 23, 2019)  
What is a mite group and vermiculite group?

Tanmoy Karmakar said: (Nov 29, 2019)  
Kaolinite group is Minimum swelling and shrinking properties than other groups.

Mayur said: (Dec 8, 2019)  
What is Vermiculite group?

Ali Zafar said: (Dec 12, 2019)  
Only Answer B is right. Actually Illite is a group of closely related non-expanding clay minerals. Option C and D are directly responsible for swelling. Option A is near to right but B is clearly non-expanding material.

Jasmin said: (Jan 3, 2020)  
As pet NPTEL, swelling of montmorillite> illite> Kaolinite.

S K Gupta said: (Jan 18, 2020)  
Kaolinite no change.

Illite medium change.

Montmorillonite maximum change.

Ammu said: (Feb 22, 2020)  

Abhisek Yadav said: (Apr 15, 2020)  
Kaolinite soil : No swelling no shrinkage.

So, A is correct answers.
