Questions & Step-by-Step Solutions

What is the role of water in cement hydration?
  • Step 1: Understand that cement is a powder made from various materials.
  • Step 2: Know that when cement is mixed with water, a chemical reaction starts.
  • Step 3: This chemical reaction is called hydration.
  • Step 4: Water helps to dissolve the cement particles, allowing them to react with each other.
  • Step 5: As the reaction occurs, new compounds form, which help to bind the materials together.
  • Step 6: Over time, this process causes the mixture to harden and gain strength, turning into concrete.
