If 60% aggregates doesn’t pass through the 2.36mm sieve, then what would be the value of Aggregate impact value?
A. 60%
B. 40%
C. 25%
D. 100%
The question was asked in an internship interview.
This key question is from Testing of Aggregates in chapter Aggregates and Testing of Aggregates of Concrete Technology
Right choice is B. 40%
The explanation is: Aggregate impact value = (W1/W2)*100
= {(100-60)/100} * 100
= 40%.
