Correct option is B
The abrasion resistance of mineral aggregates used in concrete is commonly evaluated using the Los Angeles abrasion test:
Los Angeles abrasion test measures the resistance of aggregates to wear, impact, and abrasion.
It is widely specified in standards for aggregates used in concrete and pavement works.
Why other options are incorrect:
Le Chatelier → Used for testing soundness of cement, not aggregates.
Izod → Impact test for metals and plastics, not aggregates.
Micro-Deval → Measures abrasion in a wet condition and is more common in some specifications, but the usual and most widely accepted test for concrete aggregates is Los Angeles.
