Which of the following condition should be satisfied, if an aggregate is said to be Elongated aggregate?
1
The greatest dimension (length) of aggregate is greater than 1.8 times their mean dimension (mean dimension referes to mean of sieve size through which a particular aggregate passing through and retainied on)
2
The greatest dimension (length) of aggregate is greater than 2.5 times their mean dimension (mean dimension referes to mean of sieve size through which a particular aggregate passing through and retainied on)
3
The smallest dimension (thickness) of aggregate is smaller than 0.9 times their mean dimension (mean dimension referes to mean of sieve size through which a particular aggregate passing through and retainied on)
4
The smallest dimension (thickness) of aggregate is smaller than 0.6 times their mean dimension (mean dimension referes to mean of sieve size through which a particular aggregate passing through and retainied on)
