Which test is conducted to check the resistance of aggregates to weathering?
- ACrushing test
- BSoundness testCorrect
- CImpact test
- DFlakiness index test
Solution
Concept
Soundness test
Step-by-step solution
1. Soundness is tested by repeated cycles of immersion in sodium or magnesium sulphate solution.
Explanation
It measures resistance to weathering and freeze-thaw.
Why the other options are wrong
Crushing, impact and flakiness tests measure other properties.
Shortcut
Soundness = weathering.
Correct answer: B) Soundness test
