What is the main chemical process by which cement develops binding properties after water is added?
Correct answer: A. Hydration of cement compounds
- A. Hydration of cement compounds
- B. Evaporation of mixing water
- C. Oxidation of aggregate particles
- D. Carbonation of fresh mortar
Explanation
Hydration is the chemical reaction between cement compounds and water. It forms binding products and releases heat, while evaporation alone does not produce cementitious bonds.

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.
