Question

In a 500 gram sample of coarse aggregate, there are 100 gm flaky particles and 80 gm elongated particles. What are the flakiness and elongation indices (total) as per IS ?

• A. 40%
• B. 36%
• C. 18%
• D. 4%

Answer 1

The correct option is B 36%

$FI=\frac{100}{500}\times 100=20\%$

$EI=\frac{80}{500}\times 100=16\%$

$\text{Total}=20+16=36\%$
