  • What is the chemical reaction in concrete?

  • The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

  • How does the cement hydration reaction work?

  • As the cement hydration reaction progresses, concrete will eventually change from a fluid to a rigid state. A possible working mechanism for SCS on cement hydration reaction and its products can be proposed, as shown in Figure 7.14.

  • How is concrete made?

  • How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
