Difference in detrimental effects in aggregate to be used in Portland cement concrete due to clay lumps and clay particles are

Clay lumps	Clay particles
Causes change in gradation when excess its limits.	This causes mixing with the other fine aggregate to mismatch its properties.
5% to 7% is allowed in Portland cement concrete.	3% of it is allowed in Portland cement concrete.
It is harmful to concrete used by this type of cement.	It is not harmful to concrete used by this type of cement.
It has flat shape	It has bulky shape
The clay lumps cannot be washed away from filter thus it is non-objectionable.	It is objectionable in filter material because it can be washed out by the water passing.
The clay lumps are restricted when it is subjected to abrasion.	It is detrimental when it is subjected to abrasion.
The clay lumps will stand odd and will resist the interlocking between the cement particles.	The clay particles will form a surface interlocking bonding with the cement particles.
It will change some properties of Portland cement.	It will not change the major properties of Portland cement.
