The aggregate impact value is primarily a measure of resistance to
Correct answer: C. Sudden shock or impact
- A. Abrasion under rubbing
- B. Absorption of mixing water
- C. Sudden shock or impact
- D. Chemical attack by sulphates
Explanation
The aggregate impact value assesses how well aggregate resists sudden blows or shock. It differs from the crushing value, which concerns gradually applied compressive force.

About Concrete Technology
Concrete technology covers cement, aggregates, water and admixtures, including their properties, proportioning and effect on fresh and hardened concrete. It explains workability, water-cement ratio, setting, hydration, strength, durability, curing, mix design and common defects, while distinguishing segregation and bleeding from general loss of workability.
